I am right now half way through cutting the butterfly shaft out of the right carb with a file. I don't have any good hack saw blades. I have a hole saw kit I thought of using but it's much too crude to hold inside the throttle bore and cut the brass plate and shaft with out causing a bunch of collateral damage. The heads of the screws were buggered so I have to cut the dang thing out in two places so it will all come out. I hope to finish this part of this project tonight. Going to try running the stock jets Bill.
