With that comment you’ll get no help from me, because you just bit the hand that was trying to feed you. I probably don’t know what I’m talking about, that’s why I asked the question. I’m a retired teacher, you didn’t read my signature. I’ve only been working on small engines for over 50 years, have probably rebuilt more engines than you have repaired, at one time was certified by six manufacturers, and have had students who own their own businesses. Guess I don’t have enough experience to meet you needs, or expertise. You sound far smarter than me and most members on this forum, but someone might be able to help you out one of these days, until then I would just crank the hell out of those governor screws. You don’t want them coming loose.
