Ok, so i bolted on a new magnetron coil to my 71 flathead, added some fuel, pulled the cord and boom! It fired up!.....then died quickly. Im sure the carb needs total rebuild. I added some fuel to the carb and it fired again. While pulling though, the cold pulled out of the handle and sucked into the recoil. How do i fix this? I want to keep the shurod original.
