It's missing quite a bit when it gets warm.. at idle in park I cannot notice the misfire at all but when I put it in drive , and the idle is low it randomly misfires or starts bogging down, even died on me just now. My hesitation issue might be when it is missing because sometimes it just goes and other times it chugs, I might have to try another carb this weekend... The carb is pretty old, 7-10 years.
