Hi all-
I've got a silly question... I've tuned my Edelbrock 1405 and 1406 a few times on my car (Usually after disassembly, and re-assembly for some reason), and I've always followed the same procedure:
1 Turn in on idle speed screws
1.5 turns on idle mix
Adjust linkage so they're operating "Evenly"
Fine-Tune the carbs identically
Check for Vacuum signal at manifold vacuum (w/ 2 Gauges) and set evenly as possible at idle
Is there any more fool-proof way to adjust, tune, and sync the carbs?
Another question is, does it really matter which carb has the choke (Front or Rear) with the stock linkage? I have mine in the rear, as "normal" for a 409, but a friend argued that there should be virtually no difference, and his arguments make sense on some levels..... I just put it there because it's where it was in 1963....
Could someone review their multi-carb tuning procedures with me? Especially if you've got a lot of experience with this stuff (Aubrey and the like), it's my first go with multiple carbs, and I just don't think I've got it quite right....
Any help here would be greatly appreciated, and maybe a good post in the Tech section (hint, hint...)
Thanks much-
