Was having issues with my 37. Thought it was carb / fuel pump related, but it may have been intermittent spark from my corroded rotor tab. Popped off the crab style dist cap and noticed soot on rotor tab and greenish corrosion on underside of crab dist cap. Cleaned up both and (fingers crossed) didn’t have any start up issues, even after heat soak from setting after a drive.
PS - a buddy recommended investing in a vacuum gauge. Solid investment!
Here’s my result on the 37.
