[QUOTE="Tom Gaynor, post: 9810, member: 4034"] [b]Float levels on 289's.[/b] I've been plagued since i got my twin by a front pot much sootier than the rear. I'm now running 180's in both, rear plug looks good, front is as black as the Earl o' Hell's waistcoat. Something Big Sid said about float levels, and the twin difficulties of finding out 1) where exactly the float level is, and 2) the apparent impossibility of finding out where it ought to be in terms of the carburattor itself, prompted an experiment. I tilted the front carb on its stub so that whatever the level had been, it was now 1/16" lower. Encouraged by results, I tilted it further (anti-clock looking into the bellmouth) to drop it another 1/16". Bingo, eureka, what a bloody difference. The motor was noticeably smoother, and the front plug was now brown, albeit dark brown. [/QUOTE]
