Carb Question

[bmxmon]

65 and 66 were the only years of that size rear end, it grew after 66. So either its from 65, 66, or narrowed. Check inital timing, and again vaccum leaks around the carb/intake. I had a problem before that there was another vaccum hook up on my carb and i didnt notice it, so check that out. Intakes seem to like to leak out the back where you cant see them very well, so look that over. When you time it make sure you block all your vaccum lines off. Also, when you adjust your carb keep leaning it out until it starts stumbling, then turn up the idle. Its possible your dumping too much fuel in there. Good luck, hope ya get it figured out.

Alrighty, I took it to the shop and they helped time it out, put an electronic timing system in and a new vaccuum advance on it and set it to a high idle on the carb. Runs pretty smooth but is still pretty hard to start in first without having quite a bit of shimmy. The only way I can get it to start smooth is if I lay on the gas and let the clutch up really slowly....and I know that is going to kill my clutch really quick. I looked at the rearend to see if there was a ratio tag on it but the only numbers I could find were 4K2 stamped on the differential. other that the shimmy she runs wonderful:-)...but I would still like to figure out the shimmy so I can drive it without tearing up my clutch.
