The ZAMA company says In their video you don’t have to buy any of that stuff, any good straight edge will do fine. Just put the straight edge completely across the top and check to see if it barely touches the top of the needle valve lever. That’s the setting you want end of story.
In the ZAMA corporation video titled how to rebuild a ZAMA carburetor at the 10:28 mark he says “ANY STRAIGHT EDGE WILL DO “ Which makes perfect sense, because all you’re trying to do is get the needle perfectly level in that tiny chamber works fine for me runs like a charm. And best of all it didn’t cost me a nickel to adjust.
I have found many levers that were wrong from the factory with those tools. The less expensive trimmers is where I find that. Those tools are worth having for the price even if you only use them once because you have a better chance for success after your carb rebuild. They were a game changer for me years ago. Great video my man
Thanks my friend , didn't have an idea about the needle valve gauges. But then I just don't like working on 2 cycles either . Thanks again - you just keep educating me . 👍
Ok, however, you mentioned that your metering lever is too high but the wyk stamp isn't in the middle of that tool. It's on the straight edge side. The middle is for wt, wa, and wat carbs.
So, without this "special tool" what id the clearance from a horizontal to the lever, using a set of feeler gauges? Where can the actual spacing be found ??
Hey....this may be a silly question....but,I kneed your advice. To be clear, no matter which Walbro carb model you are working on, you pretty much use the center of the Walbro W tool to set needle height movement.
I have the walbro tool and have to use a few times updating a couple of carbs on my redmax blowers. It can a little tedious but if you take your time and are careful its not the hard. You are the master small engine mechanic buddy! Keeo the great videos coming!
Thanks. I'm struggling with a carburetor problem on my 2010 Tanaka-Hitachi leaf blower right now. It's a Walbro WY series. I bent the metering lever up a little to eyeball the specified ~0.05" and got some improvement. But waiting for the Walbro tool to arrive to get it right. Thanks again for the clear and well presented video.
It really helped me, the last few days I was looking for information on adjusting the needle in zama carburettors in my native language, it turned out that looking for something in English is much easier, thanks to you I can finally adjust my brushcutter so that it works properly, thanks: )
Suggest that if you are using AM kit, the button on the metering diaphragm may be a different length from the one removed. Have set to spec & reassembled to find either flooded or starved after a few seconds running. Some equipment replacement carbs are uneconomic OEM or not available AM, or just won't tune / settle correctly. Generally great advice for OEM refurb kit.
Correct, the length of the nub on the metering diaphragm that presses on the metering lever can vary. This is especially true in the case of off-brand diaphragms. Checking to be sure the metering needle is ever so slightly lifted off it's seat as the metering lever is fully depressed, usually works quite well.
This was awesome man thank you. I just bought a new carb for our little dirtbike same carb as the first one. I took it apart and cleaned it and it still doesn’t work right so I bought a new one. I’m gonna try this and see if that’s it then I’ll have a spare carb. Thank you
Thanks for the video! I was about to throw away my chainsaw! My carb is a Sama CIM and was able to see in your tool that is a flush setting. Thanks again it worked perfect!
As I have seen many of your inspirational vids, you certainly know your stuff, I am a bit puzzled when you showed how to set the metering lever on the walbro , I seen an illustration from a walbro page apparently looked all legit, and the diagram showed that wyk imprinted on the tool would be the side used to run across the metering lever but you showed the centre of the tool being used to set the lever?
I Bought new walbro carby and it didn't go well as expected.. I did the tuning and adjustments for the idler, but I keep having the free wheel turn even on idle.. I also bought a new clutch but the wheel keeps turning.. After watching your video, Im speculating on the metering lever as its also consuming alot of fuel..
Your Amazon link is for knock off versions. Are they as accurate as the US made ones, like you showed? Does it matter, so long as they are close to the OEM tools? Anyone know for sure? Are these copied metering tools accurate enough?
Quick question Iam doing a top end job on my blower and my question is on the new head the intake and exhaust the intake and exhaust hose screw holes should they be tapped
Just rebuilt carb and everything is running good. Runs better than new. Forgot I had these gauges and didn’t check the lever. The exhaust has a little smoke like it’s burning oil. Is it fine the way it is? It has excellent response and runs great, but don’t want to burn up the piston. Done that before.
good video . thankyoudo you know if that exact same tool will be used to set walbro WT carbs as i could not see that stamping anywhere? If not can you give me a spec? I did not find one in the kit nor on the web.
Hi do you have the part number for the metering diaphragm please, ever time I order a kit the diaphram only has two holes and nothing on the other side for the petrol.
Thanks. I wasn’t totally sure which area to use. On the edge there is that little tank that sticks out of the tool. Is the for that specific model carb or is that just a tab from when they build the tool and just where they would break off that tool from the next beside it?
I learned a lot with your video but I can’t get my wt668 to work well again. I’ll clean the whole carb and will work for a minute then just boggs under acceleration. It’ll stay idling though. Idle goes up and down without touching it too. Do I just need a whole new carb and save me the headache?
Im wondering if this is my issue with my dolmar 4 stroke weed blower. at present it starts pretty easy but if I squeeze the trigger all the way it sounds almost like its stumbling but if i let off the trigger just a little bit it end up woring just fine. If this is the problem should I raise it or lower it
Sorry, meant to leave a thumbs up but accidently hit thumbs down. Subsequently added a thumbs up but fear the other will remain. Your videos are always well done and helpful. Thanks.
Hey Mower Medic quick question why is it important to find the model number of your carburetor on the actual tool is their reason just asking I'm not trying to be a keyboard cowboy
Will a lever that is just slightly high by about a millimeter or two cause an air filter to get soaked? I bought one second hand and the guy did some repair work before selling it but I've had an issue with it leaking from the carb over. I took it apart and found that the lever was slightly high, other than that from other videos I have watched the carb looks fine, the fuel lines and the tank too.
hi good day im from trinidad changed an oem carb for a stihl fs 280 brush cutter had 2 open carb to ajust lever only then i got d thing to work .Sometimes the guage thing may not always work
So why on my Stihl FS90 does the purge bulb not draw the fuel up? I have replace the carb with the China made kits twice now. It gets a trickle but by mid season I have to use a shot of starting fluid or it won't start and then it runs fine all day. The fuel lines and vent have been replaced as well as the carb.
@@THEMOWERMEDIC1 Thanks. Same exact kits I purchased previously. OEM Zama. Thinking back that is why I replaced carb the first time after replacing bulb and still getting no fuel. After I start with starting fluid it will pull a very small amount into the bulb. Guess I'll just make sure to have starting fluid on hand.
And I have to ask, what is the actual measurement of the Walbro protrusion below the sides. I ask because a quick actual measurement would be a great thing to post. Would make people actual check theirs and verify... Not sure how many would forego buying the gauge for that adjustment if their carb ran okay before disassembling them. JMHO
Not too proud to ask but do you have a video on where the hoses go on the carbs? For ex, which one goes to fuel filter and primer bulb,ect??? Thanks in advance
Mowermedic I also need help on a troybilt trimmer TB685EC that has 3.nipples on the purge bulb unable to find good information on how to route the fuel lines to the carburetor.
@@jerrysoutherland662 Hey jerry looks like about a week ago he has a video titled Correct fuel line routing (and i cant remember the rest, havent watched the whole thing yet). If you click on his name on the video (ex, Mower medic) and from there it will take you to his page. At the top click on videos and it will have his whole playlist. Hope that helps
I did not understand if something changed in how we would place the tool if the carburetor model was different from wyk since always no matter how we place it the three sides would touch if the central adjustment was done correctly

@@captaintruth3219 Any straight edge will do to span the base, then measure down from there, for your carb..
Not all adjust like that. Several models do but not all. Some are recessed down quite a bit with Zama and Walbro.
This guy knows what he is talking about. I am a small engine repair technician.

Great informative video... I adjusted metering lever slightly up on 2-stroke weedeater and went from no-start to first pull start.
Thanks my friend , didn't have an idea about the needle valve gauges. But then I just don't like working on 2 cycles either . Thanks again - you just keep educating me . 👍
Hello I didn’t see WYK for middle or did I miss something ?
Outstanding video.Thanks for your clear explanations and illustrations. Keep up the great work!

There’s another Walbro metering lever gauge. It looks like a W but it’s like the W is leaning. There’s a few Walbro carbs that use this other gauge.

This video is a gift that keeps giving! Thanks
Thank you for your time putting this short and to the point video up. I had the tool but needed a good refresher course in how to properly use it.
Thank you so much for this video, this spring came out before I had time to see where it came from . You have saved my day .

Unfortunately while bending down you can stretch out the pivot point on the lever causing slop.

So what would make it go out of adjustment, if no one troubles it?
This guy has a serious nail biting problem ? That said, he explains the process perfectly. And most important, he explains WHY it has to be correct.
Very professional video, concise. Thanks!
**The mower medic crushes another video***
Laying some serious knowledge.
Mass respect🙌
When you have the tool you feel more like you know what you are doing, even if you don't ha ha!!!
Hi i have a walbro hda 80 carb. I didnt see it listed on the "W" walbro measuring tool.
