Daniel, I would have expected 4.5 auxiliary (Secondary) venturis with F15 emulsions when using 36 mm chokes. 145 -150 mains would be the normal size for those chokes but this can vary because of differences in compression ratio, cam timing etc). 175 - 185 airs would be around the mark. The 50 F9 idles are OK. I would run 50 pumps with a 50 bleed. These are only approximate starters and would need to be fine tuned on the road. Where do you live Daniel?

The Motor in question is an L20B with a 1mm oversize bore and standard sized dished pistons. I did have a closed chambered head on it but that shit itsef in the port walls(too thin) so it now has a decked opened chambered head with larger valves(about max size for the head) and slightly ported exhaust and intake ports. Cam is a three hundred degree unit with and extra 1.5 - 2mm of lift on the valves. Power is produced from about 3500 -4000rpm all the way up to the redline. Anyway, I have a pair of 40DCOE webers with the following specs- primary venturi:36mm, Seconday venturi:5.5, Main jets:135 Idle Jets:50F9, Emulsion tube:F15(I think), Air bleed:185. I would like to know what back bleed jets and accelerator pump jets are required for this setup? The whole shebang gets its juice via a holley blue pump with the pressure regulator set at 4psi(to high, to low?). The car is only ever used on the street primarily for driving pleasure to take the mundaness out of commuting.
