Bump...

Got "bit" again. Found the secondary accel pump needle below the nozzle screw on one of the aluminum body carbs we dynoed in October has corroded in place.

I've sqirted brake cleaner in the passage from both directions, did the same with WD-40, blasted air from the metering block passage... still stuck. Guess I'll let it sit with more WD-40 in the passage hoping it'll free up.

My OPINION at this point is that an aluminum carb that is used with fuel that contains any alcohol should be completely disassembled if it's going to be sitting around for more than a few weeks.
