I like this. The end result is the same and it's not touchy. When you have a thinnish flange with a bolt on both sides and a gasket, it tends to bow the flange away from the gasket in the middle. If you're wondering if the leak at the head gasket is real, block the carbs with a big piece of cardboard and spray away from the carbs so there's no other explanation other than a leak at the gasket. If it's there, again I would use a small bead of the same type of sealer on both sides. By far the easiest solution. You said you rebuilt it, so the gasket is new.Permatex (I think?) makes a fuel resistant, non hardening gasket sealer... I had to use that on an intake mount that just wouldn't seal up with the typical gasket & bolt pressure. Was going to file the intakes on the head but figured I would give it a try first... I used a very light/thin coat on the mounting gasket, then any excess that squeezed out was removed from inside the intake before the carbs were put on. Let it set for about a day, and no more air leaks. It has held up extremely well, and removal of the sealer (after about 6 months) to work on the top end was super easy. Even made removing the gasket a pleasure as it came off in one piece and and nothing was stuck on the head.
If the thread is pulled out/extruded slightly, I also would recommend countersinking the thread hole slightly, maybe 0.5 to1 mm, to be 100% sure.New mounts won't necessarily eliminate an intake leak. If Mr. Cavewrench went neolithic on the screws at some point, the holes can become extruded and prevent the mount from sealing. If you find raised edges, use a flat file (and some flat files aren't, check first!) with light strokes, followed by 320 paper, to level the surface.
when I turn the choke off my idle goes up. Shouldn't it be vice versa? My Idle should be goin down correct?
