Sounds more like when the reinstalled your carb after cleaning, they did not ensure a proper seal from the carb to intake manifold. This is common! It could be no more than an intake leak. Start your motor and Spray a little WD40 just behind the carb on the intake seals. Be carefull not to spray into the throat of the carb as this will cause a false reading. A variance in the idle of the motor when you do this indicates an intake leak.

I have a CS4518 Earthquake chainsaw that will crank fine when you pump a little gas to the carb, but stops as soon as it burns the gas. I have replaced all fuel lines, primer bulb , cleaned the carb and...

Hi, OK firstly when you pump the primer bulb the primer bulb pulls fuel from the reservoir and pushes it to the carb then after around six to ten pumps the carb chamber is full and the fuel then goes back to the feservoir. Normally if you have a leak on the fuel line you get air in the priming bulb. Next thing is having primed Put the choke on full and pull the engine over a few times untill you hear it fire. Then depress the throttle and put the choke lever back to normal run position and pull the starter a couple of times untill it starts. Thats a pretty fool proff method on all two stroke machines and I have a few. Hope that is of some help.

Yamaha sr125 shudders then stalls when accelerating

Hi, Tybeale and the usual suspects are:
1. Idle circuit and transfer ports clogged.
2. Air fuel mixture adjustment too lean.
3. Pilot jet clogged.
4. Faulty accelerator pump.
5. Float level too low.
6. Float bowl contaminated old fuel, water, dirt, rust, etc.
7. Float bowl vent or overflow tube clogged.
8. Fuel flow to carburetor restricted.
9. Intake manifold leak.
10. The gas cap is not venting properly or fuel tank venting system blocked.
11. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
12. Needle and seat stuck closed in the float bowl.
13. Multi carburetors not in sync.

Yamaha dt125 runs on choke

The cause of this in most gas engines is a plugged jet in the carb. It must be taken apart and thoroghly cleaned. The jet must be unplugged with a stiff wire or paper clip if it will fit. Carb cleaner alone will not do the trick.

Yamaha sr 125: choke is pull and twist to lock on, the twist part does not work so choke will not stay on unless it is held out by hand, any ideas!

Hi, Badgerbrooke replace it for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

I have a coleman powermate premium plus 6250 generator,put in new plug ,new filter ,changed oil,cleaned the carb,put in new gas. runs ok at half choke but when go full choke it starts backfiring and runs...

if you are running the engine at full CHOKE, then it is flooding the engine, but if you meant off full choke, then the carb is still stopped up. Try soaking in carb cleaner overnight after removing jet & all rubber goods. HOPE THIS HELPS.

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

Strange thigs about YAMAHA TW 125

I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.
