I'm working on my latest bike, a Sears Drover, with the original engine, a H35. While taking apart the motor for the overhaul, I marked the stator bracket that holds the coil. Later, when setting the ignition timing I found the original position was way more retarded than it should have been. At least it was using the .065 thou measurement. I have a problem using the dial indicator to find TDC. Using a piston stop to find TDC is a better way to do it, I think. I'm given to understand the later model H35's used a .030 thou or so figure. Was that some emission measure or what??? I don't understand why one would be different than the other. Does anyone know what the degree figure BTDC actually is? I think I would just as soon use a timing light and a remote battery. My motor is running great with the procedure I followed, so I think everything is cool. Just wondering.
