Reworking a Carb for a Friend. 3/29/20

Have a Buddy who’s building up a Generator Shovel this Winter, came to mounting the carb and he decided he needed to get the CV Carb to move closer to the engine, to get more leg/knee room. So, I found an aftermarket carb adapter that had the 2 bolt flange on one end, and the slip on neck that’s typical for mounting CV carbs. As anyone who’s worked on an Evo or early Twin Cam, the carb doesn’t really bolt on, it’s pushed onto the carb manifold with a rubber doughnut going between to make the seal. Then you bolt the air cleaner to the engine and that pushes and holds the carb in place.

Well, we cut off that long neck in the carb adapter on the lathe and just kept the 2 bolt flange. clamped the carb in the lathe and turned the mounting spigot smooth and round, and then turned the hole in the flange on the Bridgeport to be about .004” thousandths smaller. The flange went into the toaster oven, (I have my own in the shop, cheaper than a divorce), and when it got to 250 deg, froze the carb spigot with some liquid propane and pressed them together. Voila, a CV carb with a permanent 2 bolt shovel type flange!
