Re: Where do the dots go for TDC

Post #9 shows the dots together, which means number 6 should be firing. If you put the dizzy at #1 firing with the shown cam timing, your engine will not run because the cam just finished closing for the exhaust stroke and starting opening for the intake stroke. Firing the plugs 8* before TDC on the exhaust stroke does not make an engine run. The timing dots together at te 6/12 position vs. the 12/12 position is nothing more than a double check on yourself. Treat it as such. Whether you want to stab the dizzy in at #1 TDC or #6 TDC, or any other TDC is up to you, but it HAS to be between the compression and power stroke by referencing the cam.
