Thanks again Mike. I think you are absolutly correct, and I am going to
stop worrying about this idle screw business. Now for more important
matters, need to pick a gear ratio and lockers for the axles... 33x12.5
Dana44 rear, Dana 30 front, 258, t-5. Thinking of a Powertrax no-slip for
the rear, but can't decide on the front -- with 4.56 gears.

My Weber is happy at 500 to 600 RPM. I can idle it up higher or down
lower using the screw. Webers don't light high supply pressure. Some
have had good luck with pressure regulators. This must be one for
around 4 psi. If you use a large range one and turned down to this
low pressure you'll kill the flow also and starve for gas. I put on
an electric fuel pump of this pressure rating and everything is
groovy. Another cool trick if your installed on a one barrel manifold
is to turn the carb 90 degrees (bowl toward the driver's side fender).
With a little float tweeking mine will not stumble or load up unless
it is rolling onto it's side (don't ask). It also won't flood going
directly up hill. I hope this helps.

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. :)
