<02 carbs and such> Weber mileage and things

     A few digests back the question was asked about modified 02's and gas
mileage. I been running 45 DCOE's on my 2002 for 18 years. Granted I've got
them tuned just to my tastes and have a very good linkage and manifold setup
but they have NEVER stranded me and have gotten over 20mpg under almost all
conditions. I gotten 29mpg @70mph on trips and get 23-25 with a 50-50 mix of
town and hiway. I get about 16mpg at the track. The car was a daily driver
until 3 years ago, its got 390,000 miles on it. Yes, its been rebuilt a
couple of times, each time with new tricks I've learned. There is nothing
better for a normally aspirated motor  IMHO. They can be a bit trick at first
but are not the unreliable monsters some make of them. 
      The basic spec for my setup is: 45 DCOE/ 36mm venturis / F9 emulsion
tubes with 125/195 main/air jetting / 50F8 idle jets / 40 pump jets / BMW
manifolds bored to 45mm/ custom cable linkage /Allison(now Crane) electronic
ignition/ E12 head with minor porting, stcok chambers, 9.5 pistons and a
Schrick 290 cam(a hardface copy of a Big six cam) / Tii exhaust manifold / OD
5-speed with 4:11 limited slip.
       It passes Wa state emissions testing without any trouble. At idle 518
ppm Hc( 900 limit) 4.6% CO(6.0%) under load it drops WAY down 045 ppm HC and
1.8% CO. The standards are the same until 1974 cars. Later cars have tougher
standards and the idle standard gets harder to meet.
      I'd be happy to respond off digest to anyone with DCOE questions.
      TIA for the bandwidth
