Since I have your attention may I ask about problem with my TD049 that let ot this spinner discussion. I was having a world of trouble getting my TD to start and stay running, it would either start, burn off the prime or flood completely! I was using my tried and true gravity feed system I have used on all my other engines but when I lowered the tank to exactly level with the carb it started and ran immidiately. However if I raised the tank just ever so slightly it affected the mixture adversly. Perhaps my needle valve is incorrect? Going full fuel to nothing in 2 clicks? I am looking for any advise.[&o]
