Have you done the basic things like adjusting the idle mixture and checking float levels?

What plugs do you have and what ignition system?

Thanks for the response, idle mixture screws are turned WAY out, and metering rod tree has been raised a fair amount. The engine needs these settings to idle. Float levels, everything else is at factory settings for 9800 TQ. Ignition is Chinese HE I conversion with autolite plugs that say 56 on them. I have colder denso 3257s on the way. New wires.
