 carb tuners
i have a jeep question for everyone...
I have this Motorcraft 2100 i am adapting to my jeep, everything is hooked up and plumbed, and i have reinstalled the thing ten times now and i am finally sure i have eliminated all vaccuum leaks.
It seems to be running lean. I have this newly rebuilt carb, going to my newly rebuilt motor, and then out a set of new Pace Setter headers (painted black) and on through the 2" exhaust....
while trying to tune this carb, the jeep sounds good, but the header tubes are glowing red at the block. the paint is almost completely cooked off at this point.
how worried should i be? I dont want to burn out my exhaust valves, how do i figure out if this is the proper burn in cycle for the headers or if the engine is running dangerously lean! I have played with the IMS screws through their full range of adjustment and it doesn't make a difference to the headers?! There is not much else to play with on this setup, its a pretty basic configuration.
what do you think?
where is TLRman hiding?  |
