It's been awhile since I asked this, so I'll ask it again. The Tecumseh Vector engines with the carb that has the plastic bowl that's held in place with a bale. I've never been able to make one work after it seems to wear out. I know if you buy the $18 bowl assembly and swap it out, the engine runs great. Anyone have any luck cleaning/troubleshooting these carbs without replacing the bottom end? I've, seriously, taken them completely apart and cleaned every nook and cranny with no luck.
