Brandt, Another thing to check is the screw holding down the condenser. It could be loose. I had the same thing happen on my 440 cu. motor in our 70 Imperial. Over time the screw worked loose, only missed upon full acceleration.

Say, I'm still having trouble trying to figure out why Melissa still has flat spots during FULL acceleration! Can it be a 'fluctuating' accelerator pump in one of my carbs? I hope not because everything else really is already ruled out. My fuel pump is new. My fuel filter is new. Electricalwise, my coil is good (new), my points are correctly set at about .018 - .019, I believe my timing is correct but I better recheck it? The dwell is correct right at 36. Can I have a fouled plug? As for my timing, it is advanced at about 14 degrees and I DO have the correct 98 - 100 'concacioun' for it! Can it be a faulty vacuum advance? Michael Jenkins, a Mopar expert that used to work with Jeff Carter once suggested that California this time of the year has poor gas quality. I seem to remember when she had flat spots 4 to 5 years ago, then I seem to recall when winter was over, I didn't notice the problem anymore at all. Maybe I have debris in my tank but everytime I check the filter, it appears clean. I will say this; several months ago I was pouring gas into my G from a 5 gal. jug (of racing fuel to mix with the 91) and the hose accidently fell off and down into the tank she went! Could that maybe be my problem? I think however I remember problem before that though. Anyone have suggestions and thank you kindly in advance!! ;-D Sincerely & 300ly, Brandt H J with a G.
