'95 900ss carb idle circuit settings
I've been doing some work on my new (to me) 900sscr which included cleaning the carbs. I'd never cleaned carbs before, but it was full of gelled gasoline(?) and really needed it. I cleaned the jets etc and in the process I'm not sure I replaced the idle jet correctly. Let me explain: as I understand it, the idle circuit is made up of an idle jet and the idle screw. The both are removable, but only the idle screw is accessible from the outside of the float bowl. Now before I fully understood what was going on, I may have misinterpreted the screw settings for the idle screw to apply to the jet. So I while reassembling the carbs I think I set the idle jet 2.5 turns out. I need to go back in to verify this, but before I do, what is the correct setting for the jet? Should it be seated all the way in?
Lastly, in regards to adjusting the idle screw I keep reading that turning the screw out makes the mixture more lean. But it seems to make the mix more rich (sluggish response, higher Rpms, fuel smell in exhaust). Am I just totally backwards?
Anyway I can't wait to get these setting right and get rid of this flat response at the bottom of my throttle!
