I never did the coating stuff. I became real good at using fishing line on jets. It took a couple times to realize throw the tank out. That was like eons ago. I had prospective employer staff questioning why I did not just buy a motorcycle. Some was cost an the other was learning experience and fun doing it. I thought that this was a useful thing to mention of my background. But now retired I think it was just questioning over an over same as a stress test. If you can't just be, ah well still have a Briggs bike that is California OHV stickered legal and always has someone asking how did you build that. Rangers I met never saw self build either.
