whats up with this pw 50

my sons pw 50 ran fine than we went to start it wouldn't start the only way to start it is put a 17 mm socket in my drill and spin it for 2 min and it starts then it runs fine till it cools down again.i have 90 psi compression it has a blue spark that looks good and i removed the carb and cleanedwhat could it be ?its a 1994 pw 50

i have 2 new plugs tryed them both timing were would the timing marks be?the thing is that it runs very good after about 2 mins of drill starting the thing but after i kill it and sit for 5 min its back to the drill

i dont know how to test for a good or bad spark its blue not yellow and it looks good.i was going to check the reeds but the guy that had it before me must of striped the 4 screws that hold the intake on now i have to find a way to unscrew them so i can replace the reeds.im replacing the reeds becouse when i was blowing out my carb i also blew out the intake that was still hooked up to the head and i must of blown the reeds out or off becouse now when i turn it over i hear no difference when i twist the throttle no bogging sound when you give it full throttle so im shopping for new reeds online somwere.the bike starts normal after i got it going and it warms up it only takes 1-2 kicks and it starts but when it cools noway will it start it take 1-2 min of drilling it to start to fire.i also went through this carb twice and cleaned everything (me and my buddys are all car nuts and we drag race and we tweek with carbs all the time there were 3 of us here trying to figure this thing out)the spacer was removed i think if it was between the pipe and the head then yes nothing was there when i removed the pipe.my compression is at 90 psi but i dont know what the specs on these are.if the reeds had some dirt or cracked how would it run or would it run ?

got them loose havnt taken the intake out yet but will tomarow and ordered boysen reeds for it.to crank engine there is a cover just infront of the kick starter about 3 inch round cover that covers the rotor,generator and there is a 15mm or 17mm nut that spins clock wise
