I have a 92 yamaha 350 warrior rebuilt the carb new stater and pick up coil I have it in time and plenty of spark and compression but still wont start.....

check fuses--battery and wiring

Go to the on/off switch and see if it's shorting out. Also check the ignition.

did you check the timing, piston, or put your thumb over the spark plug hole to feel for compression?

Replace the idle jet (don't clean) with a new one from a Yamaha OEM only $5.00 & make sure the idle mixture adjustment on the bottom of the carb. is set 3 1/2 turns out from seated in (a brass screw ---Don't over tighten & break off the needle tip). Also , be sure the choke is all the way off or it won't idle either.

95% of the time it's the Stator / Pulser coil in the L.H. side of the motor.

hello, you probably need to have your stator checked out, sometimes the pickup coil in the stator will go out, also you can try ign coil, the one spark plug wire is hooked to,warriors are bad about cdi going out, mine would idle, would not rev up, would bog down, source coil in stator probably needs to be checked also..

Could be a bad coil, coil wire or module. The module converts the pulses of the stator so the coil knows when to spark. Bad coil = no spark. Bad coil wire = no spark to plug.

have your carb. rebuilt and make sure there is not anything in the intake tube between the carb and the engine.

Try checking the switch for your parking brake. It is the top wire in the clutch handle boot. This wire connects to your CDI box, and restricts the RPM's while the parking brake is engauged. To find out for sure, trace the wire down to the plug under the headlight assembly and disconnect it. Now try starting you machine and give it some throttle!
