[charger1]

hello to all my mopar brothers and sisters,

i have a 70 charger R/T with a 440 4bbl.  the carb is a holley and i have a problem with the idle.  the idle will float beween 900 and about 1200 no matter how many times i have adjusted it.  anyone have any suggestions. 

thanks

prolly need more info on the gines build(cam intake comp. etc) but possibly a vaccum leak?

I have to say that 90% of the time when I hear this problem, its because one of the vacuum ports on the base of the carb is open either from a line falling off,  or a cap missing because of age and drying out, cracking, and breaking off, or otherwise.

Not saying this is your problem, but this is the first thing I would check if I were you while you give us more information and check on the easy stuff....
like spraying an unlit propane torch on the base to find a vacuum leak, or having the idle circuit on the carb not functional due to a need for a rebuild of it.
