Air/Fuel Mixture on newly rebuilt OEM Carb...
Okay, so did the 'F*&% the .22c mod' to my Carb
(YouTube's "KLR 650 Carby Mods").
It's back on the bike and it was running 'last night (big night... BIG!)...
When setting the Air/Fuel, was instructed to:
'initial setting of Air/Fuel Pilot screw is 2.25 turns out', then
'screw in Pilot screw 'til engine almost dies',
'screw out 'til engine revs too high (counting turns)', and
'screw in half the # of turns you screwed out 'til it revved to high',
and that's how we make our Air/Fuel Mixture.
Having said that, she's running beautifully (no test ride just yet... coupla things to finish off),
idles smoov, sof and silky (12-1300rpm), and
I'm anticipating runs as intended (we'll see this weekend, and I recognize this needs to happen to further 'test' the carb).
My Q is this:
How do I know when I've set the proper Air/Fuel Mixture? It seems to me that MANY settings, albeit all pretty close to each other, would run the carb effectively sitting on the Lift like it is.
I've heard of smelling the exhaust (excess fuel), etc, but I wouldn't really know the indicators of 'too rich/lean'. And I understand 'TOO' of ANYTHING can really put the hurts to a Motor.
SO, how will I know I've "set it right" because, right now, despite my results, I'm not so confident it's correct to ensure no future Motor damage.
