Degree a camshaft.

finding TDC is job one when we rely on a donut attached to our crankshaft with a rubber band to tell us...put a pushrod in the sparkplug hole with the piston coming up. turn the crank until you feel it hit and mark it (gently if the pushrod is wedged in there) , turn crank the other way until you feel it hit again and mark it. Bisect the 2 marks and you should have your TDC.
