My advice is ditch the carb and tank completely, then remove the governor.

You can buy an adapter (or make one if you can weld) that allows you to run a slide carb like a pz22 on the Flathead.

You still haven’t replaced the spark plug so don’t rule that out yet.

Did you set valve lash at TDC on the exhaust or compression stroke? If you don’t know the difference, that could be a problem.

depends on how fast you want it. Keep it stock and do a stage 1. If you remove governor, you should do flywheel rod, springs, and throw a decent cam in there for good fun.
