I just got my A4 running smoothly and thought I'd toss this out there.
One of the fixes was replacing a messy clogged carb with a fresh clean one.
While I'm sure this isn't an earth shattering idea, I rigged the electric fuel pump to an separate manual on/off switch in the power line, so even if the engine key switch/power is on, I can turn off the electric pump.
Why?
After seeing all the filthy clogged up carburetors that sat for a long time between runs, I figured having a switch in the line would let me cut off the fuel flow to the carb so the motor could run till the carb is empty. That would leave nothing to gunk/evaporate/clog the carb bowl.
I've done this on generators, outboards, and just about every kind of engine who's life includes sitting for long periods of time.
Every one starts right up when the switch/valve is reopened.
Obviously this won't help with a mechanical pump, but if there is a method to do it on that system, why not?
My original E27 tank has an on/off valve near the fuel line connection. That would serve the same purpose.
Just so happens I'm using a separate outboard type fuel tank at the moment, so that valve wouldn't work for me at this time.
Comments welcome.
