I've put new o-rings everywhere that matters. I'm bench testing float height on a 2x4 in back of my truck.

tang had about 1/16th of a gap, and the flaot height was 1/4" above the gasket. (too high)

bent the tang up to 3/16th of a gap, and the float height didn't change. at all. still 1/4" or so above the gasket.

my carbs floood 3 seconds after starting the bike, if it starts at all.

o-rings seem to fit fine everywhere.

jets are tight. needles are seating fine.

what gives ?

As in gas spilled out into the airbox, or the bike just stopped running, or both?

Were there any symptoms when you started adjusting floats and changing the o-rings?

Nope. Please explain.

Put the fuel line back on, pull the bowls and turn the carbs on their head.
Blow into the fuel line - it should hold back the force of your lungs. If you're trying with an air compressor - make it 20-30 psi.
Send it to me and it does get blow tested. How else you thing I send carbs time and time again with the floats set perfectly. People adjust air screw, and that is about it. 90% of them dont even need to do that.
Yea send it to me, and a few lincolns it will come back running like a swiss watch.
Cool.
