Fixed my carb long time ago. Runs good as it gets now. Idles all day long. All you-tube videos great. So much help. Was new to scoots last year. Inherited one from friend. Fixed everything. I can do quadra-jets, Honda 750 fours, syncho. Thanks.
Hey man, due to finacial issue's, I cannot afford to take my scooter to a garage, so trying everything I can to get it started myself, it has run so well, then after two weeks of standing still it wont start at all, drained the old fuel off, put new fuel in, put a new spark plug in and checked for spark (definitely had spark and gave myself a shock too!)....so my next step is to check the carb, I have never done this before, I had an initial inspection today and couldnt figure out how to remove he throttle cable, so your video has just shown me how! thanks man!
Thank you for this video. I have a Kymco Super 8 that needs the carb cleaned/rebuilt. I was unfamiliar with the procedure to access and remove a scoot carb. I watched a few videos here, but yours was the only one that made me feel ready to take it on.
extremely professional level job not only on the scoot maintenance, also the way you present it. clear, concise...might be too good for a yt vid. i have a kymco agility 125 that is acting cranky lately. shops tell me its probably the carb from sitting, but don't know if i want to get into the diy of everything. but really a nice job all the way around. that is very kind of you to make a presentation like this for folks looking to save some cash on their scoots! i may just take a shot at draining the carb to see if i can get it to run again. kick only when it has sit for days and then when and if it comes alive it runs like the day i got it! then it just won't kick.
I am trying to remember where my vacuum lines go on 2007 GY6 (Baja SC50-2). has 2 from petcock and ports on crankcase and air intake . I think one from crankcase goes to petcock. But which goes to carb? I watched your video and saw you disconnect a line from carb but don't know where it went. Thanks
Thanks Joe! Glad you enjoyed the video! I have a lot of excellent videos on my channel that cover many different subjects, so be sure to check out my extensive video playlists for other videos of interest to you, rate thumbs up, and share my channel with others.
Plz help..... I have an atv Chinese same carb.... But when I turn the engine on, and i let go the gas, i shuts off, i already adjust the screw on the gas cable, as well as the idle screw (pin) any ideas what can it be??? Also where does the hose that's on top on the carburetor go?? Does it go to a little nipple in front of the carburetor, where the carburetor and engine meet?
@@electronicsNmore my 150 scooter has carb issues I do my own but this is stumping me the diagram is wet with fuel I put a bigger main jet runs like 💩. I'm putting in a carb rebuild kit the whole anchalota. Diagram, needle, floats, etc. All of a sudden starting running like 💩. Rebuilt the entire engine crankshaft, starter clutch etc. Ideas?! 😃
great video, very well presented. cant keep my scoot running and now it wont start, probably due to old gas who knows. I will take mine off and clean it, either that or get a new one. I also have the 150cc/157QMJ not sure if its long case though. How do you tell? thanks for the video it was very helpful. God bless
@@electronicsNmore I have actually adjusted the valves on my scoot several years ago in 2012 shortly after I got the scoot.but I will watch the valve video. Im sure it will be very informative
Should the needle on the diaphragm move free in and out or should it be stuck to the diaphragm? My scooter is running very rich and I have tried everything
+sean crawford Hi Sean. I sold my scooter when I moved. Unfortunately I cannot check for you. Are you sure you cannot see that detail in the video? I thought it moved free.
Really like this video. Its very thorough and simple. The others ive seen takes the whole carb apart. but youre clean and inspect in sections/ Saved to my favorites.
Do you have a diagram of the regulator rectifier you made? Any info in that? I been looking at the trail tech, universeal rectifier regulator, it's fullwave, and doesn't work with the stock stater, I guess the mod you did is required, any info you may have, would be a help, thanks, do you still have the scoot??
after attaching new carb. 50cc still won't start. fuel does get to the carb. and there is spark. but yet nothing. when I poor had directly into the intake it does start. any thoughts?
I wouldn't use a brass bristle brush on the float needle seat. I take a q-tip, snap it in half, dip the cotton in polish, insert q-tip into drill, and polish the seat. That seat should be very shiny. Fixes a leaky seat every time. BTW, you won't get lost in the crowd, with those shorts on.
My 125 scoot starts up and idles for a about 30-60 secs,at around 1600rpm then cuts out! It will continue to cuts out until around 3 miles of riding until warmed up? Would this be the auto enricher not working? Thanks
+electronicsNmore - Question. Is there a way to remove the drainage line (the one with the coil) from the carburetor? I tried releasing the clamps but discovered that there was a black line running under the coil, and this line did not seem to be able to be pulled off like the rest of the lines. Thanks!
Says he added a fuel shut off valve near the tank, but that is not shown in the video. I wonder why that part was edited out of the video or why it was not taped.
Can you make a video on were the fuel filter goes I brought an new carb for my 150cc gy6 scooter an had someone else install it but now I am not getting any gas to the carb
+Jonathon Myers Hello John. If your scooter has a fuel filter installed, it should be on the fuel line between the gas tank and carburetor. If you are not getting any fuel, then you may have a faulty petcock(fuel shut-off valve). Try bypassing that valve. You will see a vacuum line connected to it along with the IN/OUT fuel lines. Thanks For Watching! Be sure to share my videos with others and rate thumbs up.
good morning to all, I disassembled the carburetor gy6 125cc to clean it as your useful guide showed. I do not know how to put the fuel lines to the carburetor, can you help me Thank you

electronicsNmore so the manifold vacuum on my new carburetor is covered up with plastic, not cap but actual plastic fused to the nipples.On my old carb there was a hole in the manifold vacuum, so I'm just wondering if I should drill through the plastic or not because the vacuum line isnt complete when its covered
I've been having a problem with my scooter when riding... When riding at higher RPM, it goes fine for a little and then stalls. After, I have to crank it excessively to restart. I theorize that when going, my float bowl is being drained out faster than it refills, causing stall and needing excessive crank to refill. I have a brand new mikuni (sp) vacuum fuel pump that I inspected before installation, so I know it isn't that unless the 35L/H rectangle ones are too weak, and now I'm pretty sure through process of elimination that it's my floater. Maybe it gets stuck closed when I fill the bowl up? and then it drains over time... of course then I wouldn't be able to refill it via cranking... ugh, diagnosing my issue has been the biggest pain... any ideas on what it could be? I idle like a champ, but at 45 mph I make it about half a kilometer before it just cuts off
Next time you have the problem, immediately try using engine starting fluid, or some gasoline sprayed into the air intake. If it starts right up, then you have a fuel system problem.
Well in experimenting with the problem I've narrowed it down some more... since I had to drain the carb to work on it, the problem became all the more obvious. Fuel isn't making it to the carb (I put my filter for outgoing on the end, about 3-4 inches before the carb fuel inlet, and I can clearly see that it is not filling... I start up fine with starter fluid as always, which tells me that my problem is somewhere between the tank and the carb... All of my lines are clear though, I blew through each just to ensure that before installation, and my vacuum pump is new and of quality brand so that's fine... The only thing that puzzles me is the hose setup, I did it the way it came, but my scooter came to me pre-assembled by the dealer so maybe they messed up from the beginning? I have a gas tank unlike what I am used to seeing, it has 2 ports on top (actually 3, there's one at the very top near where u fill it is capped off, much smaller than the other 2) and only one of those 2 ports actually is going into the fuel inlet for the vacuum pump, the other is connected to a T and is having gas go back in from the outlet. I presumed that was done like that to prevent vacuum pressure from building up inside of the tank and eventually being greater than the pump's capacity, but I am now looking at it as the most probable culprit. Any experience with something like that? I'm more experienced with petcock style, elevated fuel tanks, so IDK if maybe that's all wrong... seems like it could be as simple as raising the fuel line going back in the tank so that fuel will go to the carb until enough pressure against the float is built up for it to go that way, or maybe uncapping that small port to allow air to fill the tank as fuel is drained from both of the other ports... I'm just glad to finally have the possibilities down to a minimum lol
The fuel level height is suppose to be around 18.5mm. If no one ever touched the float, then you should not have to bend the tab on the float to adjust the height. More important is that the plunger attached to the float has a good seat.

actually my petcock has two lines total. one is fuel
I'm sure you'll be able to find pictures online. They're all different. In the video, the hose pinch tool is on the fuel line in.
What is the small hose that is L-shape not attached to anything? 50 videos and no one says what that is. Mine fell off from somewhere.
That large rubber diagram, above the main needle. I'm struggling to get it to fit properly. Did you fit it while it's completely dry?
It shouldn't be any problem installing. Make sure you're installing it correctly.

Why bother showing it? Most people won't have one, or have one in the place where I added mine. I explained what to do very clearly at 7:40.
