I am guessing that all 3 should be replaced. I would also hazzard a guess that someone may have previously bent and possibly broke the tangs during service some time back.
Ding said:You guys are putting the metal ring back in place between main jet and the nozzle right? I have looked inside many TM carbs and rarely found the plastic fuel retainers weakened to the point that they are loose enough to fall off. They are loose fitting and should freely spin, but when in place they should not slide up and down the nozzle. If they do slide I would replace them. They cost less than $10 a piece.
I'm trying to think since I've had a couple round slides apart lately and think the ring you're talking about is similar...
IIRC there is, what I'd call a brass shroud washer between the main jet and nozzle, correct? If so, yes it in place. This is what the baffle is supposed to snap onto.
I have been running without them for years and thousands of miles without an issue.
