LD340 Can’t Get The Carb Base To Seal

Typically no- they would eventually suck thru. I ended up using Allen plugs. Like the kind used for set screws in Industrial pulleys. That and pipe dope- the white sealer for making up pipe joints.
That's actually what I meant, use PTFE tape or dope on the carb stud/bolt. I didn't even think about using an allen plug. Fix it instead of trash it.
