The 74 850 I've been working on has a Mikuni that started ok when it was warm, but now that it's cold all I can get are a couple of backfires and, at most, two or three cylinder firings like it might start. After two or three of those it's back to nothing. But if I let it sit for two or three minutes I can get a few more cylinder firings. I have noticed that there are a lot of cracks in the rubber between the Mikuni and the intake. As I move the carb they grow or contract. Have to replace that, that's for sure, but it did start pretty easy with warm weather. And which is easier to start in cold weather, an Amal carb you can tickle or the mikuni?
