Marshall: The new motor is in, great improvement. I had a few details to attend to with regards to air cleaner and header to exhaust pipe and a hose from air cleaner to valve cover. All taken care of it was time to "address" the issue that was observed at the shop as well as the 50 miles of use so far. It requires full choke to start hot or cold. When warm it must be immediately pushed back in. And it has a stumble off idle. The mechanic said it was the accelerator pump. I'm not convinced but I found that the ignition dwell was not correct. I adjusted that, timing, idle speed. Once running it is just smooth as silk. Any suggestions?My carb will work. Couple mods you will need to make. Cut the primary shaft on my carb so it doesn't interfere with yout PVC tube. Gently bend your fuel line so it connects to the front. I do it all the time. Mount the air cleaner. You will need to use a stud to hold the carb down. I drill a hole in the top of the air cleaner and then use a stud. Your cable will fit my cable carb I sell for 315.
