compression test.

condensor test, or, replacement with one of the new burn-proof ones.

I don't have an issue with the modern upper plate as long as its not a wireless unit and it has the higher price quality points.

Improper fuel flow can be a real issue, but, it seems like you have that checked. Running with fuel cap loose is an easy way to check the cap for venting.

Spray the intake area to check for a leak and check to make sure the bolts are snug.
