weber 44 tuning on 2056 build
 

Used the 4 to 6 mm smaller on venturis to set up. Intake valves at 42mm
venturis at 36 . Multiple 4.1 x 36 equals mains at 150 air correction at 200.Car still pops through carbs when cruising around 3,000 RPM.If I go wot car responds great. Any help in fine tuning
Thanks,Shelton

You need to check the idle jet size. At that RPM you are not running the mains yet. Make sure they are not clogged and that you have adjusted the mixture screw.

About to install 44's on my 2056. Hopefully all we be fine. ;)

Idle jets are brand new 55,s. I talked to Al a week or so ago,told him at idle gas analyzer 4,600ppm .Im thinking way to advanced on timing issue, dizzy set up at 32 btdc @ 3,200 rpm.Any suggestions on which distributor to run,running 050 with crane xr700 optics

Most people use 40s on that sized motor...
