Hi. I need your help again. 327 in a 54 chevy pickup running a 4160 I think 4 barrel. Stamped with B1850-1. Started running rough at tickover as I came home today and I see that the two rear barrels, I take it these are the secondary's are flooded. Where do I start? Once she had cooled down, I did start her up and check the float height. Both seemed good. Just a little leakage if I rocked the truck a bit. She ran absolutely fine then but I took her for a spin and I live down an unmade rough road so I have to trickle down for about half a mile. She started to yet again run very lumpy and slow on tick over. I whipped off the air filter and there was a lot of fuel sitting in the two rears again. Any advice will be greatly appreciated.
