Vendor says no gaskets are needed; carb just sits on insulator and there's also no gasket between insulator and manifold.
1. Is that correct?
2. Anybody have a torque setting for tightening down the carb on the manifold studs? Don't want to crack the insulator.
3. What should I use on the threads for fuel and vacuum line fittings to seal? | | |

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.
