AC Weller Engine / Re: Ignition Timing - 12 1/2 before T.D.C.? Or differently with modern fuels?

Hello Eddie,
Again I am no expert, but I don’t think you check the ignition timing on the flywheel.
I think it is on the front pulley, the one that drives the water pump.
There should be a mark for Top dead centre and one for (I think 10 degrees before) top dead centre.
Make sure number one cylinder is at Top dead by removing the sparkplug. Then wind the engine backwards to the 10 degree mark.(or guess it). Then use a light or multi meter to set the distributor till the light just goes out. Lock it up then run the car to get warm.
With a strob light you should see the mark on the pulley move anti-clockwise as you rev up the engine. It should move round relatively to the engine speed. More revs the more the mark will move.
