Not sure about that particular one however if it has been sitting for a while or has a bad fuel filter the low speed jet in the carb is probably clogged. Your local lawn mower shop should be able to fix for much less than the motorcycle shop.

sure sounds like something in the carb. just for fun crank it with your hand sealing the carb intake and see if you get gas on your hand. sometimes that'll clear up things. if your hand stays dry its got a fuel problem. older machine prob needs the valves adjusted too.

My suzuki ATV quad runner cranks & idles but when you give it gas-spits and sputters/YOU MASH THE STARTER BUTTON asgiving it gas/runs fine.starter stays engaged whole time

Hi, Todd 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. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.
8. Air/fuel mixture screw set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.
11. Faulty fuel pump.
Good luck and have a nice day.

You are running really lean. gas is not getting to the idle ports. try removing the idle mixture screw and shooting some carb cleaner in there. make sure you get all of the mixture screw parts out first. Reinstall screw and set to previous adjustment. you may have to back out the idle mixture screw a bit to allow it to idle properly. There is a very small idle mixture jet that may be clogged as well.

Wont idle

Not knowing if you know anything about idle speed settings, idle mixture, etc., first check to see if all carburetor components are fully in place and are in good shape. A vacuum leak will cause the symptom you are describing. After doing that, adjust the idle stop screw. If it just won't idle even after doing that, take out the idle mixture screw, blow out the screw hole with compressed air, and gently screw in this screw all the way in. (DO NOT FORCE it.) Then open it 2.5 turns. Adjust this screw for a good strong idle while adjusting the idle SPEED with the idle stop screw. Get assistance if you don't know how to do this stuff. Good luck.
