Good another rainy day morning to all:
1959 TR3A - AUC878 H6 carbs - rebuilt with new shafts - replacement type fuel pump 2 years old.
Car starts idles on choke speed fine no fluctuation all is well, turn choke off, when temp at 185 idles at steady 600 rpm fine, drive away evrything fine - good power. Drive about five miles and wait in line at bank. car idles fine at 600 rpm, after about three minutes of standing idle drops to 500 rpm another half minute later 450 idle gets real splashy, hollow sounding, and getting ready to stall, blip throtte (great term I cannot take credit for)idle right back to a steady 600 rpm after another minute same scenario plays out. Drive car away everything runs fine again, idles at stop signs, and traffic lights A-OK. Once home I let it sit in the garage at idle and after about four minutes it starts to drop again. Is it possible the weather might have something to do with it temps were 91 (F) with very high humidity? Actually it sounds to me like it's not getting enough fuel at idle? Or I guess it doesn't like waiting around and shuts itself off.
I can't get into it until next week (graduation parties) so I was wondering what you all think?
