Best Mechanical Fuel Pump

Mine just did it again out on the highway but this was the worst one yet. After the first round of posts I reset the floats right at the bottom of the windows and its been fine for about 100miles, went out on the highway drove like a dream went to a little car meet and when I left nailed it on the on ramp and settled in at 60mph and the car was surgeing. Thought it was odd but figured I'd look when I got home as it was 15mina way and I had no real tools.

Came to the first stop light and the car dies as soon as I let off the throttle. Got it running after about 5 -10min had to hold the throttle wide open and checked under the hood sure enough carb was wet with fuel and it had a small puddle on the intake I mopped up. Got the car running again but it wouldn't idle for crap. Bucking surging and popping through the exhaust pulled into the residential street and it cleared up and ran just fine again.

Checked the floats at home sitting right at the bottom of the windows aagin, idled good etc. Going to check the fuel filter and bowl again for crap but this is a new tank that was just cleaned out this winter, 4 year old braided hose, a new carb this summer as well.

What I find odd is how long it took to clear up this time. I have a good re-useable fuel filter on the car so I don't think its crap in the needle and seat but the fuel tank also has a sump in it which might mean I suck more crap up on a street car?
