With the crank gear installed as it's pictured. The zero mark on the crank gear installed at the 1 thirty position. puts the piston at TDC on #6 firing
Let’s take it a step further........
Assume that with the dots lined up like in the pic, the cam centerline is exactly where it’s supposed to be, which in this case we’ll say is at zero advance/retard.
And, it’s a single pattern cam with symmetrical lobes.
Where is the cam relative to number 1(and where is the piston)?
