Idle Problem? HELP!

I took apart the carb, cleaned it all out. New gas. New sparkplugs. Choke all the way open. Idle screw all the way up. Had to spray either to start it but it starts on its own, but sometimes not. Got it to run with hand aways on throttle. Then then H ppipe got cherry red! What do i do?

Your fuel mixture is too lean.Need more gas.Need to adjust your carb.When you say idle screw do you by any chance mean the mixture screw?That one should be set at 2,5 turns counterclockwise from full in position.The idle screw is the on that lifts the slight with the needle.That one should not lift the slight barrel more than 1mm from the bottom.You will adjust it again later while the engine is running to reach 1100rpm.

Poulan 222 38cc choke problem; choke has to be kept out for it to continue running. Carbeurator has been cleaned.

Sounds like this saw has had gasoline with alcohol in it and the idle jet is plugged up. Have to take it apart and use a small wire to open the jet. Just cleaning the carb will not solve this problem. With the idle jet plugged adjusting the idle screw will accomplish nothing. Then us gasoline with no alcohol in it from then on. Search with google to find a station that sells non alcohol gasoline in your area.

'07 klr 650 won't run without choke on

Hi, Lance and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Vacuum line from the petcock to intake manifold cracked.
5. Float needle and seat sticking.
6. Float level too low.
7. Carburetor bowl vent line clogged/blocked/pinched.
8. Idle adjusting screw set too low.
9. Air/fuel mixture screw set too lean.
10. Idle port, transfer ports, slow air jet clogged.
11. Slow fuel jet clogged.
12. Faulty fuel pump.

Hi I am rebuilding a 1979 suzuki enduro I took the carb apart and cleaned it ..It idles great but when i get on the gas it Bogs down and quits any info or parts catalog or manual would be great...I dont...

check the air box and filter for obstructions.

The mixture screw should be fully screwed in gently and then undone about 1 1/4 to 1 1/2 turns.
The idle screw is only in operation during idle, then slide then comes into play and then on fuller throttle settings, the needle and main jet take over.

If rebuilding it is imperative to have a good workshop manual/ some are available online.

Poulan 2375. Just replaced all fuel lines. Only stays running at greater than 1/2 choke. Have never had to adjust carb before. Maybe an air leak around carb? Easy way to check for that? Any suggestions or...

First I would start with the fuel filter, was that replaced too?, then I would make sure you have fresh gas and a new spark plug, Probably what I would suggest next is to pull your carb off and take apart and clean it with carb cleaner, most likely you will find dirt and possible small fragments from rotten fuel lines,partially plugging the inlet screen in carb, also your diaphram could be stretched, wouldn't hurt to pur carb kit in it while it is apart, I have just cleaned them before and been o.k. this should help you out

I let my bike sit for asbout 3 years and now it wont stay on

The pilot jets are still gummed up. This jet controls the idle port and usually gets overlooked. To clean it the jet must be removed along and the adjusting screw as well. The circuit must be cleared of gum. For each individual carb, when removing the jet and the adjuster, count the turns then remount that number of turns. Now turn the adjuster screw 1/4 turn counter clockwise.

Yamaha TTR 125 L won't idle

this is very tipical. when bikes are stored the fuel varishes up the jets & needles. soak the carb. moving it back and forth in the soak solution. then blow every jet and orfice with a controlled air source. note: any speck of rust or dirt can plug these jets. pay attention to detail and do every thing twice. then install the carb and adjust it to your riding style. later Spike
