Hi guys. It's my turn next. Engine suddenly stopped running, no fuel pump action, no valve action, but seemed to have sparks at spark plug when trying to start......

So, I've located parts @ greenparts store. A few questions.

I plan on doing the work my self (Should I be concerned?)

Should I replace the waterpump at the same time?

Anything else while I'm in there?

How are cam/crankshaft gears marked for timing?

Can I mess-up the spark timing during this job? (I don't know whether the spark timing is from the cam or a pick-up on the flywheel)

Thanx Ed B

ps: Any other veterans of this work have advice?
