I had no idea the rough starting was due to the valves needing to be adjusted. I immediately ordered a kit and wow. What an improvement! I adjust the valves on my 3 classic VWs on a regular basis so I feel like a derp for not realizing this is what my Kombi needed. Thanks so much!
Enjoy your videos very much. The fuel hose came off inside the tank because the nipple on the plastic adapter is smooth. Stihl updated that piece many years ago to a ribbed nipple on the plastic. No more fuel hoses falling off. It comes as a kit for the four mix. Never reuse the smooth ones. It will bite you in the end. As for the carburetor, no rebuilds from experience. Much smaller orifices inside and if the primer bulb is that bad, the carb is not far behind. Valve adjustment at EVERY tune up. After so many of those drive shafts coming apart, you need all the tricks you can fiind. A lot more fun when they are in the shape of an ess. Just another day at a Stihl shop.
About 2 months ago I worked on a Stihl FS90 that was given to me. I did the same exact valve adjustment to get it running. I converted it to a hedge trimmer. Now it runs great.
My 130R trimmer was hard to pull to start. I took it back to the dealer and they said that is how they are. Now I had owned it for about a year. I got the feeler gage and the parts. Watched a few videos on what to do but no one said anything about the 2 different top dead settings to where the valves are. I believe I seen a video you posted on the correct way to do it. I was totally off. Now it pulls so much easier. Thank you!
About 8 years ago I saw that same model pole-saw for sale on eBay for $600 with shipping. It was used but looked new and had the tools and everything. I bought it for my son and it's been a trouble-free workhorse since. It's a hand-full when extended to the full 16' but sometimes you just need it all. It's a great product just like our Stihl chainsaws, blowers, and trimmers. Great info on adjusting the valves. Thanks!
Thanks Bre, this might be the solution to why my old FS 85 trimmer won`t start & run. I saw how USPS is slowing the mail down so hope you still get the delivery by next week.
Try cleaning the spark arrestor, mine did the same thing, was about to order a carburetor and decided to give the spark arrestor cleaning a shot and it worked like a charm.
Looks like the customer had these sitting for a few years before he finally bit the bullet and had them looked at. My neighbor has a FS 85 trimmer that ran like poo. Thanks to your guidance, it now runs like a champ. Thanks from both of us, I learned how to fix it, and he has his trimmer back. BONUS, I can now borrow it when needed!
I bought a four mix that looked like that. Had a lot of the same symptoms yours had. Did a total teardown, clean, grease, and replaced some parts. Runs great now!
I've had the "pleasure" of diagnosing one of those,first time I had ever seen this system. One other notorious point of failure is the PLASTIC camshaft,which will be mangled when the valves need adjustment. Another 6$ or so part,will save you a lot of trouble to just replace while it is opened up
Nice job. The valve adjustment is a regular maintenance item. It says right in the Owner's Manual to adjust the valves every 130 hours. No one ever does it and then they complain that the recoil is hard to pull and the engine doesn't have any power.
Another great video where you make it look easy. The back pain is the WORST!!!! Speaking from experience. I hurt my back in 2004 hauling trees and now I have to stretch 2 times a day to survive. Hopefully you’ll heal quickly. Thank you for sharing your video
Hi Bre, I know what that kind of back pain feels like. I needed two back surgeries for my auto accident injury. The spinal fusion surgery relieved about 75% of my low back pain, but another rear end accident five years later made all the pain return. Have been on pain management since 2000. There was one time, before the fusion surgery, I was loading up my pickup with unmounted 10:00 x 20" truck tires for our dump trucks. Our family owned a fleet of dump trucks and I was the mechanic/driver. Well, I needed to load up eight tires and on the last one as I was flipping it onto the tailgate my back went out with that screaming pain knocking me to the ground and I couldn't get back up. I was at home and had to crawl back into the house through the back door. Luckily there was a phone on the desk in the basement I could reach to call my father for help. I would not have been able to reach any of the wall mounted phones. He was able to get me on a sofa in the basement and I stayed there for several hours until the pain subsided enough to head to the ER. It wasn't long after that event I had the fusion surgery. You, Ron and the family stay safe.
Oh no! So Sorry Don! The same thing happened to Ron. I walked out back of our old repair shop and he was laying on the ground by the zero turn he was working on. Had to go to the emergency room, but they were no help. Took hours just to get any pain meds.
@@Chickanic Hi Bre, I found the ER was also not much help except getting a script for some stronger pain meds. It was about a week before I could get back to work from that event.
I went back to the clutch replacement video from two yrs ago. It was interesting to see how much your presentation has changed in those two yrs. You've loosened up a lot. Nothing wrong with that, it's just obvious you've become more comfortable with the videos. Thx.
Hello from France (Normandy), I just discovered your YT channel. and I am delighted to have found the solution for my KM and my HS 45 which both had trouble starting! Plus with a video accompanied by a sensually smiling Chic Lady. it's just happiness. PS: I subscribed because you all have lots of interesting solutions. Have a nice day.🥰
After your back is back to full functioning, there are exercises to strengthen the muscles that help a lot. Will keep it from going out again in the future. I had trouble for a lot of years, until i got on the ball and strengthened my muscles. No no problem for the last decade or two. Yes, im getting up there in age, but i feel great. Thank you for another awesome video and great advice.
Hi Bre, interesting to note that the feeler gauge for these valves is actually 4 thousandths. I put a Mitutoyo 500-196-30 Digital Caliper on mine and that's what it read. There's a 10 stamped on the feeler gauge so it has to be a metric tool. Conversion is 2.56cm/in.
Bre, pick yourself up one of those elastic with velcro back braces. When you get the slightest twinge, throw it on, you'll be spared the worst. They really do help hold things where they ought to be.
Once any structural problems have been found and dealt with, the next best thing for most back problems is physical therapy. This is not to say, "Just go to the gym, bro!" but to work with doctors and physical therapists to find the routines that will best work for you and YOUR back issues.
I learned something today! My KM131has been doing that jerking thing, recently, when I go to start it. Guess I'll have to check valve adjustment! Thanks!
Yes. I had to do.that adjustment to mine a couple of years ago. Mine vibrates so much my hands tingle. Even when I have a saw balanced blade on it. Does yours? Lots of power though.
Just checked my HT75 and there is no valve cover or fuel tank plug. 😊 Every year, that dang pole saw is more of a beast to operate! Always start lopping off branch pieces from the end and work your way back to the tree trunk.
Do take care of your back! Those issues really get worse over time. At 77 I wish I could undo all the heavy lifting I did early in life (starting at $1.15/hour). It's finally cool enough to start cutting firewood for next year and this old body needs the work to keep from locking up! The lesson I learned is, just because you can do something doesn't mean you should. Good plan to let Alex do that cranking!
Every time you start a piece of equipment and right away it idles. Then I go out and start mine, and NOW they start and idle right away. Thank you from the bottom of my heart.
So I bought my fs 90 close to 20 yrs ago. First yr they fixed the gas cap to a regular screw an not that locking one. Still fires up 1st or 2nd pull. I've made over $200k easily. Ive cut between 10 an 40 yards a week every yr. A couple clutches 4 or 5 heads. Hands down the best weedeater ever made. Best $325 i ever spent.
I was hoping to see you fix the pole part too but just to get the engine running again is good. I'm not particularly fond of the design of the 4mix engine and I think the Shindaiwa hybrid4 design makes more sense since the fuel air mix actually goes up into the head and through the intake valve. I am more of a Honda mini 4 stroke design fan as those engines are incredibly smooth, easy to start and use. My Honda trimmer, unfortunately is out of commission currently as it needs some work on the fuel system like replacement lines and grommet, a potential carb kit and a new primer bulb. The machine is 18 years old and first belonged to my Uncle who has since passed away.
Great fix, i have 2 questions though. 1. Why didn't you give it a wash? 2. what juice do you use in your ultrasonic cleaner? i have one but haven't been able to find a cleaning solution that works/cost a fortune, or is that a trade secret? Top notch video as usual thanks for posting.
Stihl has an updated grommet that has a barbed end on it so the inner fuel line won't fall off. It also comes with a new inner line. Fyi. Keep up the great vids.
hello from France thank you for the video, I hope you will feel better with your back my question: can we use the oil 2 times echo power blind for stihl, and Husqvarna 2% is ok? Thank you for your reply
That valve adjustment looked weird to me. Back in the dark ages you loosened the nut and adjusted the clearance with a screwdriver in the top slot and then without moving the screwdriver tightened the nut to lock in the adjustment. How has it changed? Serious question.
They are nothing but problems.scortched piston walls,they require .10 valves adjustment,top dead center,sthil oil,long run cam gear failure,i had 4 of the 4 mixes,2 cycle kombi no problems
for my back I use heat and cold. A heating pad then a shower, at the end of the shower I aim the shower head at my lower back and then keep adjusting the water temp until it's full cold, and I'll just stand there for 15-20 minutes.
Maybe that's what was wrong with my Stihl fs130. It had a jerky start. A spark plug only lasted 5 hours and then it would needed to be replaced already. Maybe valves needed adjustment. I finally just trashed it and bought a 2 stroke echo.
Back pain what you need is a teeter Inversion chair with massage and heat. $249.00 . Well worth it . Works great for L4 &L5 Bulging disc. Just my suggestion from my experience with it.
Regarding the worn out wheel bushings at the beginning - what kind of design moron places the grease nipple on the inaccessible/invisible inside of the wheel, when there is totally the same available space on the outside?
8:20 just to chime in, i had a similar situation with a brittle piece of plastic for some plumbing stuff. the way I find best is to heat the plastic up a hair before attempting (like with a hair dryer, max of 80C), it doesn't always work but when it does it makes things supple enough that there's enough flexibility that stuff works as designed. I do agree though that it's a stupid design.
The owner of bicycle shop near me told me that people are always dropping off broken bicycles thinking that he can use the parts, he guesses. He said he wishes they wouldn't as now he has to get rid of them.
Great video Bre, as always. Hey, you’re getting really close to 500k subscribers. 👍👍. What a mess! Like they say, treat your equipment casually and it will end up a casualty.
Not like you to try adjusting the mixture knowing the valves were in dire need of adjustment.. For those doing their own work, a typical .004" feeler gauge will not work. The rocker arms are ribbed to deter push rod slippage. You'll need to trim the end of the feeler gauge to fit or buy the over priced Stihl tool.
Last time I took a piece of equipment to a small repair shop they just basically did everything. I told them I did right before I took the equipment there … then charged me a bunch.
I had no idea the rough starting was due to the valves needing to be adjusted. I immediately ordered a kit and wow. What an improvement! I adjust the valves on my 3 classic VWs on a regular basis so I feel like a derp for not realizing this is what my Kombi needed. Thanks so much!

always a good lesson learned from your knowledge on small equipment
Thank you.
I wish you covered more small tractors! Or knew a channel that did if you had no interest, trying to learn more and I appreciate your teaching style
I learned something today!
My KM131has been doing that jerking thing, recently, when I go to start it.
Guess I'll have to check valve adjustment! Thanks!
Yes. I had to do.that adjustment to mine a couple of years ago. Mine vibrates so much my hands tingle. Even when I have a saw balanced blade on it. Does yours? Lots of power though.
I have a question what is your preferred ultrasonic parts cleaner solution?
Love the Vette and the '68 Cougar ... Hope to see you restore that Cougar.. those were cool vehicles!!
Great video , thank you for all you show us.
FYI That Stihl feeler gauge is 0.10 MM or .004 of an inch .
Hi Chickanic I watch every one of your videos and enjoy every one.....A small correction..The feeler gage from Stihl is actually .1mm,or .004 inches
Very impressive fix for an ignored motor! I'm learning every episode1. Thanks!
Just checked my HT75 and there is no valve cover or fuel tank plug. 😊
Every year, that dang pole saw is more of a beast to operate!
Always start lopping off branch pieces from the end and work your way back to the tree trunk.
And the grease zerk is pristine,no wear on it at all😂🤣🤦♂️
Good observation.
What's a grease zerk for ? 😅
😂
@@markcdeyoung3118

Got a few 2 strokers, run fine with cracked, falling off, primer bulbs, some won't run at all if they have a pinhole in them.
Never knew about these small 4 stroke units very cool thanks for showing it.
4 mixes
I have the same Stihl 201TC. Mine runs great but wont start unless you hit it with starter fluid. I know i could redo carb but just havent done it
Every time you start a piece of equipment and right away it idles. Then I go out and start mine, and NOW they start and idle right away. Thank you from the bottom of my heart.
i find so many like this at the dump, half start right up! People throw so much away. Glad you could save it

What about the gaping hole in the side of the tank?
Good morning!
Hey Dave!
Stihl has an updated grommet that has a barbed end on it so the inner fuel line won't fall off. It also comes with a new inner line. Fyi. Keep up the great vids.
What is the round gizmo with a bb in the center, on the little tube? And…….. the turning must have been interesting 😮
Fixin to replace my bushing with bearings. Mine has 60ish hours. Gonna replace the spindle washers with flat bearings also. Less than $20 in parts.
Great info thanks
I clean the grommet spray pb blaster and it pops right out when you pry.
Bre you help me re-remember how to do things-much appreciated!
Thank you, keep working.
After watching your videos, I purchased myself a sonic cleaner. One of the best investments I’ve made. Thanks
Wonder.if 3d.printing a cover and beaked latch would make the fuel bib cover easier to come off
hello from France
thank you for the video, I hope you will feel better with your back
my question: can we use the oil 2 times echo power blind for stihl, and Husqvarna 2% is ok?
Thank you for your reply
THANK YOU FOR THE VIDEO
Love how you explain things. Very easy to understand. Keep the vids coming Tnx.
Nice fix on the pole saw , Bre .

They are nothing but problems.scortched piston walls,they require .10 valves adjustment,top dead center,sthil oil,long run cam gear failure,i had 4 of the 4 mixes,2 cycle kombi no problems
Sciatica is no fun if you get that too when you throw your back out, I like to keep some emu oil around and apply it.
for my back I use heat and cold. A heating pad then a shower, at the end of the shower I aim the shower head at my lower back and then keep adjusting the water temp until it's full cold, and I'll just stand there for 15-20 minutes.
Love your videos. Had a fun moment when you pulled the cord on the pole saw on your bench, just as my neighbor started his Harley 😂
What liquid do you use in your ultrasonic cleanser for carburetors?
GOOD MORNING !!
Maybe that's what was wrong with my Stihl fs130. It had a jerky start. A spark plug only lasted 5 hours and then it would needed to be replaced already. Maybe valves needed adjustment. I finally just trashed it and bought a 2 stroke echo.
Saved another one 😊
Hi- great channel! But I can’t find your ultrasonic cleaner in your Amazon store. Keep up the great work - I tell everyone about your channel.
Great video, did Sthil have issues with the plastic cams wearing out on those 4 cycle mix units?
I love your videos so relatboul
Sorry if you've already said this. What do you use for a cleaning solution in your ultrasonic cleaner? Thanks for your vids!
Invaluable, thx!
There's a kit you can buy to upgrade those front wheel bushings to actual bearings...
Can you reach under the grommet in the tank with a tool to push it upwards from its underside while you pull up on it from the outside?
Back pain what you need is a teeter Inversion chair with massage and heat. $249.00 . Well worth it . Works great for L4 &L5 Bulging disc. Just my suggestion from my experience with it.
Love you Chickie😊
What kind of cleaner do you use for your sonic cleaner
Great Job! 👍
Hope your back is better. I hate that feeling.
Where do you find the bushing to riding mower wheels.
Add fuel hose to your needle nose plyers to keep the nipples safe
Regarding the worn out wheel bushings at the beginning - what kind of design moron places the grease nipple on the inaccessible/invisible inside of the wheel, when there is totally the same available space on the outside?
What do you use as a cleaning medium in the ultra sonic tank ?
Thanks in advance !
Time for an electric garage door opener. 😀
8:20 just to chime in, i had a similar situation with a brittle piece of plastic for some plumbing stuff. the way I find best is to heat the plastic up a hair before attempting (like with a hair dryer, max of 80C), it doesn't always work but when it does it makes things supple enough that there's enough flexibility that stuff works as designed. I do agree though that it's a stupid design.

Great video Bre, as always. Hey, you’re getting really close to 500k subscribers. 👍👍. What a mess! Like they say, treat your equipment casually and it will end up a casualty.
Totally not a Stihl question but is there a right and wrong TDC for a Craftsman lawn tractor? How do we know which one is right?
Biggest problem with those is the nose cone bearings freeze up, other than that they run forever
Another awesome video. Thank you. I hope i can remember this one. 😊
Hope your back is better.
Bre, wish I had a pull starter.
Today at Home Depot got 5 8oz bottles of Ethonol Shield for $7.50 each on sale
Not like you to try adjusting the mixture knowing the valves were in dire need of adjustment.. For those doing their own work, a typical .004" feeler gauge will not work. The rocker arms are ribbed to deter push rod slippage. You'll need to trim the end of the feeler gauge to fit or buy the over priced Stihl tool.
Any idea how to repair a stripped zerk fitting hole on a lawnmower tire?
Last time I took a piece of equipment to a small repair shop they just basically did everything. I told them I did right before I took the equipment there … then charged me a bunch.
