engine problem

[StayDirty25]

i was taking my hot bodies lightning engine apart and cleaning it when i took the back plate off and sprayed the inside of the engine with wd 40 and the place where the piston it connected there was a pin that caught for the pull start which fell out. before it fell out it was sticking out some so that it would catch now it only sticks out when i tilt it back and sometimes doesn't catch at all. the engine is a .21 hot bodies stock lightning engine.

what can i do to fix this?

i think there should be a spring that goes under that pin. its very small and can easily be lost if it springs out. i believe the hot bodies engine is built jsut like a hpi s-25 so you can look at parts diagrahms for that engine.
