I’m starting to suspect the fuel mix. Or you have plugs that won’t fire under compression. Maybe it’s time for some NGKs ?
I’ll check the fuel ratio again, if I can’t get anything after spraying starter fluid into the cylinders it has to be spark plug related. I will swap those out next. Any reference on which NGKs?
Champion J6J are recommended back in 1952… NGK B6S are recommended today for replacement. I may already have these plugs 😐
