mkoch Posted May 20, 2021 Share Posted May 20, 2021 (edited) ,85 BRAT, Hitachi, 49 state, new fuel filters, old loud fuel pump, new front and rear fuel filters. The car will hesitate and lurch under certain conditions. If I let the car just idle still for a while, and then accelerate, there is not problem accelerating, until about 20 seconds into it, then the balking begins. The normal acceleration indicates to me that both carb barrels are working. I just drove this car up a 1/10 mile 7% incline several times. I let this car idle, still, at the bottom of the hill every time before I did the test. 2nd gear, 2,000 rpm, the car makes it up the hill just fine. 2nd gear, 2,500rpm, the car starts balking halfway up the hill. I am guessing the problem is the fuel pump, or the valve which fills the float bowl. Am I missing something?
