Engine 1985 Holly 4180C high Idle

[cimscott]

Woody, when I stated “Ask how I know”, I was referring to that I tried to run a normal holley carb spacer and the gasket failed due to the EGR heat burning thru.
So I just run the stock factory EGR spacer with a EGR block off plate and new gaskets.
Sorry for the confusion.

Do you have air condoning? If so there is a solenoid that kicks the idle up when the air is on. Maybe malfunctioning or misadjusted?

Was on LMR's site and they have a Holley solenoid and bracket for this... Had no idea anyone reproduced these... Looks to me like they would work on the stock carb also?
