Hi,, new here. I've been in the caddyshere (63 deville and 73 eldo convert) for about 7 years so a Pontiac is new ground. still learning however...lots to learn in both the cad world and over here.. recently picked up the above 67. 70 k miles. looks pretty much stock,,new plug wires, plugs, regular distributor, dual exhaust.
overall looks good, made the 3 hours back from purchase with no problems but after returning, noted the following.
the problem is at takeoff or after slowing down and then accelerating, there is a slight hesitation or sag in the acceleration. doesnt happen every time but is a noticeable hesitation. I thought it may be timing, so I checked that, it was at about 4 so I checked manual and it stated should be around 6 or so.. so I made it and set it about what appears to be about 7 degrees btdc.
set out again after timing change and it didn't solve the problem. same symptom. I was looking towards vacuum advance but sheer conjecture.
What would be recommended in search for cause of this hesitation.
thanks for looking,,
