,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?
