LD340 Can’t Get The Carb Base To Seal

Thanks for the replies, I’ve checked the carb base with a flat file and did remove a little material at the carb corners, not much but they were a little high. I’ve ordered a thicker insulating type gasket and studs and am waiting for it to come from Amazon. I will also move the PCV to the port on the carb, the car doesn’t have power brakes, that’s why I used that port on the intake, didn’t know that it mattered. I’ll report back when the gasket gets here and I get it back together. Thanks for the help.
