Turn the crankshaft until the valves of a cylinder are closed and then listen at the oil filler hole, the dip stick hole, the air inlet and the exhaust pipe. This can indicate which part needs work.

Be careful though that you don't apply so much pressure in the cylinder that you turn the crank. This is essentially the donkey work of a leak down test with out making the measurement...

(I hope I'm not teaching you how to suck eggs funola!)
I have read about the leak down test but have never done one myself. I should do one just for the experience.

Adjusted the valves today, #1 was a little tight but not too bad. Last time they were adjusted was about 5000 miles ago. Idle is a bit smoother. The new nozzles and the valve adjustment really made a substantial difference in power. I think there's more to go with a timing check/ adjustment.
