hey guys have this on a small block yip way to big had the combo on the dyno no drama but as soon as i try to idle/ cruse way to rich will kill the plugs has any blocked the intermidiate circuit
































hey guys super rich at idle here are the carb spec 28high speed 51intermidiate 29idle air bleed 79primary jet 85power valve 92cscondary no pv in rear mixtuer screws 3/4 turn out primary blades set so transfer slot is square cam at .050 intake250 exuast256 valve lift in624 ex605 any starters thanks

How much "steady vacuum" are you seeing at idle & cruise?

Also ...

a. Does the intermediate circuit have a removable jet type of orifice in your carb's metering body?

b. Does it seem to be a "similar amount too rich at both idle & cruise rpm" ... or is does one seem richer than the other ?

c. Are the emulsion orifices simply drilled holes ... or removable jet type orifices?

d. 3-circuit carbs are designed to be richer on the low end. So I don't normally see them in this application. Did you buy this carb for this application? Is it new or used?

e. Do you have a A/F meter you can use to help dial this carb in?

This?

I would say all the help he needs is right there. :thankyou:

I hope so, I did it to my drag car and it helped a lot

hi guys thanks for the replys here goes carb came with engine it does have screw in bleeds on the intermidate circuit thers no provison for vacume gauge but there is a blank spot at the front so will drill and tap it the emulsions are not screw in type but there is small bleeds at top of meter block on the PVside and screw in bleeds/jets right next to the main jets will purchase a/f meter i will post sum pics of the carb tomoro im in NZ so be sum time delay and thanks again also runs real rich at idle and cruise
