moving the timing mark on a Super A, C, etc.

I'm still putting the motor together (two steps forward and one step back - How did it run with the auto advance all busted up ? Five helicoils in the aluminum bars that span the front and the back of the block. etc.) and see that there are notches on the crankshaft pulley, but no pointer in the front cover. Crawling around under the belly with a flashlight looking for faint scratches on the flywheel is silly.

Any reason not to do it ?

ps Why aren't the timing marks on the crank, cam, and governor gears lined up at TDC ? The first journal on the crank is obviously to the left, and the piston is down a little when the marks line up.

As long as that's the way the designers set it up AND the marks are properly aligned, no worries.

My GUESS is that they do it that way so NO valves are being opened, or just closing which would tend to make the cam rotate back out of position, and make it difficult to install the timing gear.

They pick a sort of "neutral point", where the cam will stay put (not rotate forward or backward) while you install the gear, and make the gear timing marks at that point.

My pulley doesn't have a notch that I saw, but I did put a dot of black paint (NO yaller on the outside, thank you!) on the back of the pulley and the front of the timing cover so that they line up at TDC.
