04 Raptor 350 - High Idle after strip & clean
Working on getting a very under-used Raptor ready for sale and stripped the carb as it was running very lean, back-firing like crazy after essentially nil use for the last few years and very little use for ten years.
Clearly badly gummed up.
I've seen the other thread on this and I don't think I have a leak.
I cleaned it carefully, ensuring the slide is moving smoothly.
Firing it up, idle was very high, rpm increasing a shade after 10 secs or so. Throttle control operative, although it settle back higher still after blipping the throttle.
I made 2 mistakes that I've discovered so far, well three, starting work on something I didn't have maintenance docs for.
1. I didn't note the throttle linkage position before disassembly. I've adjusted at both ends in the closing direction as far as possible and backed off the idle setting stop, still too high. Does anyone have a photo or diagram of the carb end of the throttle mechanism so I can be sure that I've not done anything stupid there?
2. I didn't note how many turns I backed out the single adjustable part of the mechanism to clean it. (centre front, bottom when installed) I think it's the idle fuel setting and that fully in is lowest, but I don't know. Fully in did not have a perceptible effect on the very high idle. Can anyone please tell me what the "low" setting of that adjuster is and confirm the function.
What else stupid could I have done and what should I do to identify my failings?
I should add that I am competent at working on small mechanical stuff - I restore vintage audio stuff including tape recorders professionally, but I've no experience in working small engines and their carbs.
