The current procedure that I use to get the engine up to operating temp is as follows: I start the engine, let it idle just for a couple seconds then promptly
bring her up to 2.5 - 3k rpm and let it idle in that range until I hit 160 or so. I don't rev it at all. I just gently bring her up to that rpm and hold
it.
I hear there's other spiffy ways to do it just by fiddling with the carb tuning and such but I don't know much about these Webers so I'm not about to go messing with screws and jets and stuff that I don't understand. :-P I'm curious if this is just a personal preference thing or if there are definite proper ways to do this warmup deal.

advice. Yeah, I've been told (and
convinced) that blipping the throttle while cold is not good on the seals. When I have some mild jets in, I can let the car idle by itself at 15-1800 RPM and
it never fouls a plug. With more aggressive jets, (mainly the F10 75 idle jet), it will foul unless you turn down the air screw from 3.5 out to 0.5 turns out.
I warm it up while I'm getting my gear on and signing autographs. Then I turn it back up to 3.5, shut if off, put the cowl back on, get to the grid at
the 10 minute mark and let the manifold heat soak. You don't want it to cool too much. Start it back up and idle at 2000 or so with some moderate
throttle blipping as required at the 5.
