my carb showed signs of leakage which is one reason I replaced it.  I have no idea why it shows only 3 lbs now.  I tried plumbing the carb directly from a gas can.  I forgot to switch the fuel line off and shot fuel clear out on the wing when the engine started.

===============================================

I would try to borrow another carb and try it since it seems your fuel delivery system is working

  I've had two "lucky" flights so far.

I checked for induction leaks(pressurized and soap solution) and found nothing.

    ===========================

 

Do not try for three, resolve this problem on the ground!
