I have a Hot Bodies 12 engine, and it seems to me that when the
piston reaches the top of the sleeve that it is very tight and
doesnt want to move freely(sometimes is stuck). I tried oiling it
and nothing worked. I think I could replace the sleeve but im not
sure which is bad the sleeve or the piston. Why is it doing that?
What caused it to start doing that, what can I do to prevent it
from doing it again. Its a brand new motor, so therefore Im not
sure what happen. Can anyone help? My HPI stock engine moves
freely with no sticking.....am I nuts and its supposed to do that,
or am I sane and I have a bad engine?
