2many,
I just ended up on this buy chance and noticed that you really seam to know what you are talking about.
I just got 2 Yamoto 200cc, one is running really good and the other one well not so good. I am not sure if it has anything to do with the carb adjustment, but I will do that anyways.
I but my ATV on a jack and took the rear tires off. I was working on the ATv and got it running in the garage for a while. I adjusted the chain and the clutch. Next thing that I noticed was that when I was putting the ATV in gear, the chain and the rear axle where turning, even if no one was touching the throttle, wetter or not I had the clutch pulled in. At first I taught that I might off tightened the chain to much, after playing with it to loosen it up and braking a chain adjuster, I realized that it had nothing to do with the chain.
What would cause this? Also, is there an easy trick to make sure that the rear axel is parallel to the right one? Since I played with it to fix the chain, I am afraid that it might be slightly out of position.
Thanks in advance.
Dom

 

Bump!

 

Pictures of how to adjust needle

 

I have a SUNL ATV mini truck. The gas turned bad. So I drained the tank, added fresh fuel, Took the carb apart and thoroughly cleaned, and replaced the plug. It starts great and idles perfect. But when I accelerate it bogs down. If I hold the throttle open it builds crispness, it just lacks acceleration. Any ideas on whats happening here? I have made several adjustments since then. I first noticed the exaust pipe was heating up red. So adjusted the air/Fuel mixture but nothing has changed. Stumped????????

 

2manytoys,

This information is great, but I have two Kazuma ATV's that I bought new, and I do not see any way to adjust the needle on either one. The carbs are automatic choke, and the throttle cable attaches to the side of the carb. The carb has a butterfly in it like a car. The needle is vaccuum controlled. I took the assmbly out and there is no e-clip. They have not been right since new, and the dealer went out of business. Please help....

Thanks

I have a falcon 250 that I just purchased from a guy who couldn't get it to run and was very frustrated. I installed a kazuma carb and the bike noe idles perfect. however it has no power and bogs at any ammount of throttle. I replaced the intake boot next but no difference. any ideas?

 

I just adjusted the Carb on my 2007 50cc Giovanni as it had trouble idling and was bogging at full throtlle. I turned the idle screw (screw with spring) up until the machine would idle with no trouble and then adjusted the screw directly beside it (had to turn in completely clock-wise) until it would idle at the highest RPM and reset the main idle screw.

My question is did I turn the right screw for the A/F mixture and if not what screw did I turn? The machine runs quite well now with good power across the whole power band and starts and will idle perfectly.
