Engine Trouble HELP, new plug, running problems

[alpha]

i went and bought a b6hs and now the motor suddenly stops running after 5 min, is it running to hot or what never had this problem

are you sure that you've got a good flow of fuel into the carb?
It could be a fuel issue, like the float bowl may be running out of gas and slowly re-filling.
either the fuel flowing out of the gas tank os restricted (junk in the petcock), you have a clogged fuel filter, or junk in the needle & seat on the carb.
I don;t think the new plug has anything to do with it, but you could put your old plug back in and see if it does the same thing.
If it does the same thing with the old plug, then it's probably a fuel issue.

i agree put in the old plug and see if the bish still has problems

i dont think its that cause its only once the motor warms up, and it gets harder and harder to pedal but ill give it a shot

Change the plug out, but I don't think it's the problem. Most likely in the coil or CDI (getting hot). How to check then, read.

never mind i pulled off the top of the engine off, and the cyl walls are gouged and theirs bits of round metal that look like pins or something, like roller bearings or something. but now i know why its not running, wonder what it sucked up?

Pull the wrist pin and look there. Most likely that's where it came from.

on top of the piston though how would they get up that far

how small would they be, these are very small, like 1mm diam. and 2-4mm long
