i just cleaned these carbs yesterday and assembled today. the bike runs for the first time!
i could only get one cap off the check the diaphragms, but the one i looked at looked fine, but vinyl-looking??
anyway, carbs were filthy, one main totally blocked, some passages blocked, but all clean now.
did not replace any orings at this time, was just trying to get bike running. did not replace choke or throttle shaft seals.
bike runs, idles, and revs. on its own, the idle will raise up for a minute or two, to maybe 2K, and on its own falls back to idle. if you rev it, it will stay at 2k, and fall back down after a minute or so. i initially thought slides hanging, but the bike will do it on its own.
manifolds are OG and look like shit. but, i do not get the idle to bump spraying with carb cleaner while idling, so id have to say theyre sealing.
removed the caps over the hidden screw up top, backed it out to 3.5 from easily seated. was there another bleed or mixture screw that needed adjusting?
any ideas why the rpm would raise up on its own and then drop? im thinking air from somewhere, and i know i have alot of seals to replace.
