Bare with me here because I don't know all the correct jargon and have a limted knowledge of most things engine related (I have a few guys helping me out that are very smart in these fields)
I have a 75, 302 with cam and gear driven, intake and holley 4 barrel. I finally have it on the road and she ran fine in the winter. Now being warmer after about ten minutes the glass filter at the carb emptys itself of fuel (idols fine but dies under a load).
Here is a list of things done and replaced. First isse I had in the winter was that the encentic was loose so that was taken care of and I got about a month of no problems. Happened again and is still happening after replacing all hoses, filters,gas tanks and fuel pumps (it is a mech pump)(we also took motor apart and checked encentic again to be sure and it was tight and fine). I was told maybe vapor lock but we ran it straight from a gas can plumbed into the fuel pump with same results. We then iced the carb and ran water over the intake because it seemed the carb was getting way too hot and that seemed to give some of the fuel back. So next replaced the 180 thermostat with a 160 and I added a 1/2" phenolic spacer to help with the heat issues and still the same result. Now we are kind of stumped and any advice would be great. I am sure I have missed a few things and I will try to answer any comments the best I can.
