Ok - thanks for all the help! Here is an update on my 454. Dealer rebuilt the carburetor, I replaced the coil, points, condenser. I still need to run the choke at about 1/2 for anything to work decent. Every once-in-awhile it will "cough" - enough to flutter the choke butterfly. Governor doesn't move. Have not had a chance to check compression. Still runs like cr*p, but is getting better. The intake/exhaust manifold gaskets MIGHT be leaking - figured to change them anyway. Any more ideas? Dealer hates me, because I expect this thing to at least run, since my trade-in ran good.

Galen, would you care to inform us of this dealers name? We all may want to steer clear of him. I can also tell you from experience that there is no point in rebuilding a carb if you don't soak it for a few hours, preferably overnight.

My 454 gas did this to me when I first got it, had to run with the choke on for it to work. After two rebuild kits and a trip to the dealer they found a small piece of dirt in the carb and replaced the ventury. Did they soak the carb in cleaner over night to get all the dirt out, or just do a quick rebuild? I don't know why they replaced the ventury but it's worked better ever since. Still runs a little rich but It probably just needs adjusting.

Tried to get them to soak it, but, since they don't like me very much, they just did a quick rebuild. Oh well, don't much care for them either!

I'd say that might be a problem. After they charged me $110 for a carb rebuild kit (I did a quick rebuild) I gave it to them to fix. They soaked it, did a ventury and so far.... After thinking about it I belive the main orfice had some dirt build up

Try turning the main jet adjusting screw CCW several turns to see if the engine will run decent
without using the choke. Hal

Hi Galen, again no expierence on gas 454 but lots on Diesel model. If the choke has to be 1/2 closed and it still coughs then the air fuel mixture is to lean. Now this can be caused by many things:
1)lack of fuel flow to carb.
2)carb jets out of adjust.
3)float level to low.
4)vacuum leak around manifold etc. Try the old trick of spraying WD40 around the manifold and carb area while the engine is running. If the engine speeds up then there is a vacuum leak in that area. BECAREFUL NOT TO IGNITE the WD40, have a fire extinquisher nearby.
5)low vacuum from cylinders, caused by valves not closing or worn rings. Quick check is place your slightly spread apart fingers over the air intage of the carb. There should be significant air flow between your fingers. BE CAREFUL NOT TO BURN YOUR FINGERS IF IT COUGHS THROUGH THE CARB WITH HOT GASSES.
More indepth test is to compression test each cylinder.

Is there any possiblity the carb was assemble incorrectly? About a month ago someone on this site was complaining about similar problem after a carb rebuilt and someone reminded him that the carb venturi can go together in either direction and to turn it around and it solved his problem.

Are you positive that the spark plug wires are connected to proper cylinder as per firing order?

Good luck
JB2
