My atv has good compression and spark. I just cleaned the carb along with all the jets and the float is working. The back of the carb is sucking good when i put my hand over it. Im getting a little gas on my spark plug so im getting gas...i dont understand what else it can be. Im thinking is something electrical not allowing it to start or something.

05 honda 300 trx wont start

Well i just checked the spark plug gap and it was perfect.i just bought the ngk plug. So i guess the last thing is to get a new ignition coil. Oh and i still havent done a proper compression test to see if it has enough compression but it seems ok.

Do the compression test - most problems come down to low compression caused by tight valves (generally it's the intake valves that get tight)

Coils are the last thing to get - if you have any spark, it is usually:
1st - plug
2nd - plug cap
3rd - stator
Last - coil

If you know someone with one like yours that runs, swap parts off theirs onto yours to see if any of the external parts fixes the problem
