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.
1. Soaked it from both sides w/ PB Blaster
2. Got out my skinny little pick collection and tried my best to dislodge it
3. Air pressure from my compressor thru a rubber-tipped nozzle
4. Even tried to force a pick into the top of the check needle w/ no luck
Final option... and the one I did
not want to resort to... drill it out. But that's what I ended up doing cuz nothing else worked.
Then I had to take a series of drill bit shanks and resize the bottom of the hole to make sure the needle would drop all the way to the bottom and not get stuck again.
The odd thing is the remains of the check needle don't look corroded, yet this thing was completely stuck in the passage.
