    finally after 2 years of off/on work to get this 92 daihatsu running well i'm very close! only problem remaining is engine surges after shifting thru the gears. even in neutral while parked if i hit the gas and release, the engine rpm will surge for a couple of seconds before returning to idle. also after letting off the throttle to coast down a hill the engine will surge for a couple of seconds then coast then continue to surge as long as my foot is off the accelerator. i can watch the vacuum pot on the carburator advance the actuator in vacuum that moves the throttle body and high cold idle lever with excess vacuum. any advice is welcome. thank's in advance, flip

    Accelerator pump in the carb, and or float in the carb!
