as noted elsewhere, i recently r, r, and r-ed my a4. until yesterday i had been running it off an outboard tank / primer bulb combo attached to my primary filter, thence to the mechanical fuel pump, carb, etc. Motor ran fairly well, but you had to give the bulb a few squeezes every 2 minutes or so.
yesterday, i reconnected the main tank. Flushed it with fuel using the fuel pump priming lever...cloudy at first -- no surprise -- then it cleared. Motor started, ran fine for about a minute, then slowed, then quit. Would only restart if i worked the priming lever until stiff.
Eventually, i found i could keep the motor running fine as long as i worked the priming lever every 30 sec. or so.
i've tightened everything that can be tightened.
i'm assuming the fuel pump is weak or inop and will have to be rebuilt. no biggie -- but am i correct?
Also, since the motor rebuilders were earnest but not very competent, did they screw something up here also? Is there something internal that runs the fuel pump cam that they may have forgot to reinstall? in which case, i'll install an electric pump and not rebuild the mechanical one.
pls. let me know what you think...
