OK, well the top cylinder is #1, bottom is #2.
Not sure which flywheel mark is for which cylinder though, doesn’t really matter…Wont run if somehow you get the firing order mixed up! You mention you are going to just gap the points to .020″ on the high side of the cam, so the timing marks are not going to be used. Just be sure you don’t swap the coil primary leads to the wrong points though.
In order to set the point timing “exactly”, you would need a special timing tool that fits over the crank, so you can set the points precisely with an ohm meter…
But, once you have the engine running, you can use a timing light to “check your work”. With the timing light connected to cylinder number one, point it towards the two hash marks on the mag plate…Hopefully, the single timing mark on the flywheel will fall in between the two hash marks on the mag plate… Repeat this process with cylinder #2.
One final note, if you are using new sets of points, you may want to set the gap to .022″ on the high side of the cam, to account for initial rubbing block wear…
