Help, I'm stumped!

[snakebittexan]

I have a strange intermittent problem that I’ll do my best to describe by recounting the last several occurrences;

Engine, Keith Craft 408, QuikFuel carb, manual fuel pump

Sunday (yesterday) she was running good, stopped and sat for fifteen minutes, started easily, went two hundred feet in first, changed into second and died, one and a half pumps restarted, smoothed out and ran ok.

Sunday running good, stopped for fifteen minutes, normal start, while pulling out after 50 feet it cut out like it's out of gas, stopped one and a half pumps, restart spitting, sputtering, smoothed out then ran normally.

Saturday afternoon, running good, kicked it in second, same sputter, pop, died, pop clutch restarts, never in all these occurrences do I smell fuel.

Last weekend while at our Cobra rally in San Marcos a number of us got some bad gas and the problem was even worse, popping, missing, usually at higher RPM. She would die, leave it in gear to restart.The sooner I could get it into the higher gears the sooner she smoothed out. Sometimes while pulling back up a hill after a sharp curve adn lower speeds whe would spit, stutter, adn die, I would kick it down into a lower gear or leave it and she would restart and run just fine.

While in San Marcos and driving the hill Country I could kick it in third or fourth and she would start spitting and sputtering sometimes completely shutting down. NOTE, Saturday in San Marcos was hot, high 80’s—90. Coming home Sunday it was cold and damp, she performed perfectly all the way home (200 plus miles). Yesterday and Saturday were hot and problem pops up again. On one occasion after stopping for lunch she would start, die, start, die and after the last restart smelled flooded but that was the one time I could smell fuel.She usually starts easily, idles good and only the one time have I smelled fuel.

I tracked at Harris Hill Friday on "Dallas" fuel and she ran great.

I have a new coil and MSD box. After our Saturday cruise in San Marcos we cleaned the float bowls, front fuel filter and replaced the rear filter.

Any ideas?
