I see. Until just recently I have only been doing straight overhauls. I have started to do port work and lowering squish bands on my own saws. I have a nice lathe and milling machine and recently got out of machinist school. I am having trouble getting a grasp of timing on the saws. I have a degree wheel and all the tools I need I am just failing to see if its worth it to me to spend so much time on a saw. It takes a considerable amount of time to tool up and cut the squish, port and polish intake and exhaust, modify the muffler, and then get the timing right. I don't see how I can pass that much extra labor along to a customer and not eat a portion of my time. This is my only income and has been for the last year and I enjoy it enough I dont want to burn myself out.
