hey i just got this engine from some one on here and when i went to take the flywheel nut off yesterday with my impact gun the motor didnt turn over at all i didnt have to use any thing to stop the flywheel from moving cause it didnt move any..the only thing i can think of is that the spark plugs are still in could that be causing it to have problems turning over by hand?

 

Even with the spark plugs in, the engine should still turn even by hand. Chances are that an apex seal has broken and is wedged between the rotor and housing. Or the bearing are frozen

 

damnit it was said to be a strong running motor..i guess i'll try again in a few mins

 

i'ma try to put the flywheel back on and try turning it over..

 

The engine might be okay.. just some carbon got in the way..lube it up through the leading plug holes..use Transmission fluid as it will help disolve the carbon, then after about 1 day relube with oil then try to break loose.

 

yeah see thats what i thought cause when i first got it it turned over fine i kept turning and turning just to make sure it wasnt locked up and then it stoped its like somthing got in the way...but it was nice turning over sound no grinding noises

 

i went back out there..it turns over just fine now i guess it was carbon build up or somthing but its smooth.

 

Transmission fluid is kind of hard on the seals. It might work out better to get a gallon of marvels mystery oil and use that.
