You will need to give us more information. What is the brand name and model number of the engine.

Engine Timing

Ihay,

If flywheel key was sheared, ONLY IT HAS CHANGED and not
anything inside the engine. With piston @ TDC & crank journal
and connecting rod at their highest point, there is a small DOT
mark on the small crankshaft gear at around the 2 o'clock
position. The cam also has a mark on it, OR....there is a hole
in the face of the came where that mark is, also. Align the
two marks with one another and the internal timing is set.
Over the years, and in the WORST CASE SCENARIOS....I've
seen the small crankshaft gear actually moved from a blade
impact. It's a PRESSED ON gear, and a strong shock will/can
move this gear....RARE....but, can happen. Replace the key
that was sheared and try it out. If it continues to KICKBACK,
then there's other problems than JUST KEY. Good Luck !!!

Go to this site and download a Tecumseh Service manual. It should answer all your questions.
