Hey everyone! My neighbour is a nice old fella but he can't walk very good and doesn't have much money so I'm trying my damndest to help him get his wheeler running so he can be outside in his woods when he wants. I just cleaned the carb real good and put it back together and it ran like a dream! I thought I had it! But today It won't start. This has been the pattern he told me over the last few years. It'll run just great one day and then won't even start the next. Would a bad cdi be temperamental like that? I know It could be a ground and I'm gonna start stripping the plastics off and trouble shooting wires. Anybody have any suggestions of where to look first? Any help is much appreciated!!
