So, I have what I think is a vacuum leak between the Weber carb, and one of the adaptor plates that mount it onto the intake. The intake is new to me (the previous one had crack at the front that was jb welded back together), and I had it machined flat, and installed a new remflex gasket, as well as new carb gaskets from red line.
After having the typical symptoms that you'd get from an intake vacuum leak (loss of power under a load, and the smell of a lean mixture), I checked again today to make sure the carb hold down nuts were all tight, and found that two of them were a little loose. I put locktite on them when I installed them, but suspect it wasn't strong enough.
After all this narrative to paint a picture, my question is, could it be possible the adaptor plate(s) is/are warped? I've read stories where depending on the year of manufacturing, they were made in some not so quality places, with less quality control. If so (which I'll pull back apart you check later), can they be machined flat? Thanks for reading my long, but hopefully descriptive, post.
