sh and vx .18 motor problems

[drewthegun]

I've got 3 of these bastard motors sitting around now and they are all doing the same thing they start when thery cool then you run em for about a min and start giving it some hell and they just die and wont start again for ages.... is the bore too worn out and when it gets hot the motor loses compression??? I've tuned and retune and so on and thats the only idea i can sorta come up with.

check the temp before it dies.. if its WAY WAY too hot, then i would say its runing WAY WAY too lean..

That could mean air leak..Is your engine sealed?
