Thanks for the info. I am using the stock fuel pump and the k551 32/36 kit.
I can get the idle up plenty high by just cranking the idle screw in. I
need to check the fuel pressure anyway. Its running really good at the
moment, so perhaps I should just leave well enough alone. :)

Jerry, thanks for the note. I've followed the instructions to the letter,
and with the idle speed screw at no more than 1 1/2 turns in once it hits
the linkage, the idle is like 350-400 rpms. I have the idle mix set just
right, and I have to turn the idle speed screw to about 3 turns to get the
idle up to 650. The mix screw, with the stock 75 idle jet, winds up at 2
1/2 turns -- right at spec, set to lean best. I have no vacuum leaks, and
the rest of the ignition system/fuel system is tweaked just right. So I'm
going to live with the speed screw in 3 turns. I have tried 80 and 85
jets. With the larger jets, the mix screw gets good at less turns out from
base, 1 1/2 turns for the 85 for example, but the speed screw still has to
be turned in 3 turns or so to get a decent idle. I talked to a guy at
carbs.net and he said just turn the idle screw in unitl I'm happy, and that
it won't hurt anything. The carb and engine are running great with the
idle screw set at 3 turns, so I'm not complaining about performance. I
just got concerned when the weber tech support guy told me that running the
speed screw in at more than 1 1/2 turns would dump gas into the crank case
and destroy the engine.

LOL! ;-)
Redline-Weber's instructions are meant to get you to a baseline with the
idle mixture screws, you can than set the idle spee screw where ever you
want it. As a check, you may want to take tit to a shop that can check the
exhaust CO readings.
