Well I have extra time on my hands now so I want to do a project Ive been thinking about for a while now. I want to do a mild build on a 5hp BS non raptor tiller engine. I don't want to weld the block or do anything too fancy. I want to put a billet rod in, an improved oil dipper, and a cam that will not require any valve change. I have 04-3 and 7x written down in some old notes. I also want to go with a 3 1/2 cast iron flywheel only because I have a couple lying around with the coil drop-down etc. Do I just pull the plastic gov gear out and just toss it? I also already did a few carb mods as instructed in the build 5hp racing motor book. I have installed rings and pistons before and do know the basics. If anyone has a cam that may be suitable for me Im interested.Also welcome any other advice.
