[DML] Re: ACCELERATION PROBLEM

["Harold McElraft" <hmcelraft@xxxxxxx>]

Sounds to me like the fuel mixture is off (too lean). Have you 
checked it? There is a procedure to set it with a dwell meter in the 
shop manual.

happening:  Start the car up and it idles right on specs, try to give 
it gas and it wants to hesitate and almost quit.  Back off the gas, 
it goes back to idle.  As the car warms up, you can get more and more 
rpm but never full throttle.  After the car is warmed up to where the 
fans come on, the idle hunts up and down, between 650 and 850 rpm.  
The car starts backfiring if you try to go above 5000 rpm.  If you 
move the throttle off the microswitch that controls the frequency 
valve, idle stabilizes at 950-100 rpm.
