This has worked on every engine I have ever worked on. One cam 2 cams are four are any amount of cylinders. This is a reply I made to a Ford flat head so you would have to convert it to your engine
An old trick to see if valve timing is right on a flat head would be to remove the head or lifter cover and bring #1 cyl up to compression stroke. While you are rotating the engine coming up on #1 TDC, #4 should be on overlap (exhaust valve closing, intake valve opening). This should happen right on TDC #1. If a valve on #4 is wide open or doing nothing at all, the valve timing is off... weather it"s the cam gear . crank, gear or key way, broken cam,etc. The reason # 4 is the cyl in question is because that is the "middle" cyl in the firing order 1-2-4-3. The "middle Cly should always be in overlap. for instance, on a chevy the firing order is 1-8-4-3-6-5-7-2, so if we wanted to see if the valve timing was off we would look at cyl# 6 to see if it was on overlap rolling the engine over to #1 TDC. It should overlap right at #1 TDC at 0 degrees

It wasn't to relive memories of Grampa, Dad or myself out on the back 40 nursing the Farmall pulling too many b
