LD340 Can’t Get The Carb Base To Seal

I'm developing an unhealthy fascination with this thread....it has all the elements of a ****** party in a burned out apartment building. The simple problem followed by layers upon layers of misguided advice and misinformation....it's like peeling an onion of automotive misery!

It's really this simple when it comes to carb bases - if the two surfaces are relatively flat and continuous and the carb is properly tightened - it'll seal. The type of fasteners, the PCV vacuum tap location, the exact type of gasket, and all the rest have nothing to do with it.
