It will not idle around six to five hundred rpms ( dies). Have adjust gav no real help. Idles around eight to thousand rpms, also it does not start right up like it did with one b carb. I have did the wd40 test checking for leaks . No increase in rpms. The b carbs where professionally restored , flow tested , run in an other car, ect . Timing is right on . Car has a mechanical spark advance .Intake and exhaust manifold was removed from car bolted together and leveled. Any pointers that I am missing ? Any input would be great . Thanks Miff
Purdy doesnt post here any more, not sure if he reads any at all, you might try sending him a PM. I would also post this over on the HAMB under the banger thread, you may get some pointers.
DO you have a cam, High compression head, any other mods or did you just change the intake? Provide as many details as you can for the best help
Good Luck
