Question

The atv will not start when i try and turn it on. The ignition will crank but i can't seem to even get the four wheeler to idle we have changed the oil, messed around with the fuel/air intake s***w, and the idle time s***w. We are not sure on if any of these things will fix it or not. We dont know what way to turn any of the screws. PLEASE HELP me fix my four wheeler so i will be able to ride again

Answer 1

Check for spark - the plug may be fouled.

Remove the spark plug - insert the plug into the spark plug cap - lay the threads of the plug against the engine - turn on the key and try to start the engine - the plug should spark.

If no - try a new spark plug.

If yes - remove and clean the carburetor - especially the pilot jet.

The pilot jet's opening is a thin as a pin and is easily clogged with bad gas.

Go to - your quad - Carburetor - # 36

Purchase a service manual for instructions on how to remove the carb -
