Re: Set timing on 1924 Straight Eight Engine

Sorry, when you said "timing" I assumed you meant ignition timing. I guess you meant valve timing?

Why are you assuming that when the cam marks are aligned as it sounds you've done correctly, they only align when #1 is at TDC? Without direct experience with a 2nd series Eight I'd assume you've got it right, but just to be sure you should check the valve timing. Have you rotated the engine by hand in the direction or rotation and seen the intake open on the intake stroke, both close on compression and power, and the exhaust open on the exhaust stroke? It might be nice to have a degree wheel made up and check for the exact cycle, but as long as you aligned the cam and crank marks this test sould be adequate.

Or am I missing something here?
