Spark plug is soaked with fuel put in new one let sit over nite open put in new plug same thing

 

[FNgonuts]

I kinda think its in the stator have not checked spark yet

I would check the timing. Your key might be sheared. If it doesn't spark at TDC, you don't get combustion. Check to see if the plug is wet so you know it's getting fuel. Just a thought.

got spark think i have to much fuel working on it i'll check back tomorrow

check the key for the flywheel.. my buddys kxt250 powered blaster sheered the key would would do the sasme thing, sound like a12g blast... and toss a new plug in if the key is good

Ok found my problem magnet in the flywheel is busted up didn't catch it during the rebuild i did feel a slight bind halfway thu the first kik but it went away along with the end of the pickup danm thing is it fires just to weak to crank
