I had the same problem with my 440, and drilled 1/8 inch holes in the throttle plates and it cleaned up the idle nicely. If you don't want to drill you plates, you came buy plates predrilled. just be careful you don't drill to big a hole. start small and adjust from there.

Can you turn the mixture screws in and get the engine
to stall(one at a time)

You will probally need to reduce the idle and part throttle fuel feed passages What list number is it ,if it is a stock type Holley 1050 Dominator carb? I've had to learn how to do that on my old pump gas street Duster with many different list # dominators on it, them rascals be race carbs, not street carbs I ended up buying #6 brass set screws and then drilling and tapping those passages in the main carb. body and then reducing the I.D. on those pasages by around 50% by drillng the set screws. Take your time and make sure what each passage is Good luck, that motor with race gas may be a little harder to get right on the first try, don't give up

you running a power valve in the primary side? if so then what size is it and what is your vacuume hot idleing in gear. those dommys can be tricky but with a little work you can get it to idle clean all day long.

P-body -yes they stall the engine one at a time
Dartman- no power valve
idle bleed is aprox .047
Cab ..pm me your # again (the amish love their pulley set up)lol.

The reason I asked that question was to see if your
even on the idle circuit.. how far out are the mixture
screws.. I usually can set them at 1/8 to a 1/4 turn
out from the point where they start to stall the
engine(the RPM drop point)

I did try putting a larger idle bleed in.. made it worse..even after adjusting it.

Lean can burn your eyes as well................I ASSume you don`t have a wideband but how do the plugs look?

one way to tell is with your idle air screws, if you need to turn them out to gain a better idle then the bleed is too large making it lean and by screwing the idle air screws out will richen the circut, just the opposite if they are too small.

No wide band, actually is puffing smoke...bluish in color, not oil ....rich fuel plugs are slighty coated black..

Years ago, when I ran a carb on my 1050, I had the same experience. To solve it, I had to drill and fit the idle feeds to restrict them.

what is the largest bleed you have gone to, mine has #55 bleeds in the idle circuit, mine idles clean and the idle screws are out a little over 1.5 turns,, next question is.. does it take forever to warm up? when mine was origionally put on it seemed like hours to get to 170* which meant it was pig rich at idle.

Went as far as .065 still rich, warms right up. Warmer the engine richer the engine, 1.5 turns out.. run like a raped ape just rich idle, what does the intermediate bleed do.

I run a 8082 2 circuit so I cannot tell you what effect those will have, you may have to do like theotherdodge said and restrict the ifr's, you may try and get ahold of AJ Casini here on the board as he did my dommy, I have also done some reading on the Horsepower Innovations web site, they seem to explain it pretty well,,just google it or google E-85 carb tuning.

Blue is generally oil not fuel and it`s possible you compromised ring seal by running a 3-circut w/out a p/v..............

If you're going to street drive it then you should put a power valve in it and reduce the jet size. That will help clean things up a bit.

I don't understand the idle issue though. If you can stall the engine by screwing the idle mixture jets in then you have enough adjustability.

Where is the throttle blade set in relationship to the transfer slot? There should only be a small portion of the transfer slot showing under the throttle blade. Start with that and go from there.

You should not need to change the air bleeds at all.

Three things; convert to a two circuit, install a primary p/v and get a wideband.............

I know this, but it is fuel not oil, I don' understand it either.
