So I go a 73 troy built tiller with a lighting coil but the engine is stuck. I pulled the flywheel to look and make sure that it did have the lighting coil but when I put the flywheel back on the crank broke. I do have a running craftsman 5hp tecumseh that I could put the coil on. I know that I need to use the flywheel and possibly the engine shroud. Just wondering if anyone knows of any reason it would not work. The craftsman has the fuel tank.
