any suggestions for gasket/ seal fix for carb insulators

Post by tex » Tue Dec 13, 2016 7:14 am

kicked over and runs, seems to have a pretty good air leak between the carb insulators and block, (High Rev, almost sounds like shes trying to run away from time to time)

-is there a better gasket than the oring out there?
- would red rtv work between the insulator and block?

Comments, S*** or Suggestions please lol

I'd try a new o ring first. They do work. What is the condition of the spacer?

Before installing heat spacers check for flatness with wet/dry paper on glass or other flat surface do the same for carb flange. After confirming that all surfaces are flat install new O-rings with grease. If you can't find the correct O-rigs, slash cut an O-ring that has the proper thickness. Don't over tighten the carb mounting nuts!
Do what you've always done and you'll get what you've always had.

It is easy to warp the carb flange by over-tightening. After that you're on to a loser. Get the carb flanges flat and start from there.
