I have cleaned my carbs (dipped stripped, the Full Monty) several times.
This weekend, I was finally ready to test drive the beast after a massive top-end tear down.
The fuel/air mix and synching are destroying my mind, but I will work on that more before posting here. Instead, here is a side oddity.
I also replaced my handlebars, and the new position on the throttle was giving me some problems in that the throttle did not want to snap closed. I checked the cables, throttle assembly, etc. to find out where it was binding up.
At first, the throttle spring on the carbs checked out, with it snapping back nicely. Connected the "go cable" and she continued to snap back. Then connected the "close" cable, and problem returned. Most of this appeared to be from the new cable routing, because unattached, both cables moved freely in the housings. So I rerouted them until I got a good snap closure.
Took the bike for a short trip around the neighborhood. On top of some obvious mixture problems, the throttle began acting up -- failing to close quickly. The assembly refuses to stay in place on the bar, so I figured that was shifting the cable routes, and causing the problem.
I brought her back home and started working back through the cables. When I checked the slides/spring at the carbs, they no longer snapped close. WTF?
Pulled the carbs of the bike and found 2-3 of the slides were gummed up with spots of dark grey junk on them, causing them to stick. Stripped them down again, so they are soaking in Berryman's where they can "think about what they've done."
With freshly cleaned carbs, what could gum the slides like that so quickly? The only thing that I can think of is that I ran out of spray carb cleaner in the last strip down and used a bit of brake cleaner to check some passages. I figured that these two cleaners were pretty similar, as they both reek of acetone. Could brake cleaner gum up in the carbs?
