If one of the O-rings on the float valve body is damaged then it will overfill the bowls. Gus

I'm having the same problem. I ordered the o-rings along with some other misc pieces from Allstate Carburetor. Never tried them before, but seem to have good prices. https://allcarbs.com/ I should have waited. These are better pricing than the Ebay ones. I paid $11.13 for 10 shipped. Your guy alllcarbs is $6.23 shipped for 10. Plus I'm going to have to wait longer too. I hope my needles are ruined from the Q16 fuel.

Tex I do have a return system. How can this get blocked? any thing going through the system . Fuel line post carb collapsing or breaking up internally . Especially if older and you have changed fuel ? Tex

Check fuel pressure and replace needle and seats This...Verify the gauge is right too. Needle and seats, as stated, I've had the O-rings shrink and not seal. If you screw the thing out and pull it out of the bore there should be a little felt resistance if its snug enough in the bore. Make sure the floats aren't heavy too.
If the results don't match the theory, change the theory.

Carb parts are consumables just like almost everything else. I change out my floats every 2-3 years, stainless or titanium needles and seats, Gaskets, pumps, etc. routine maintenance with little costs.

There is no resistance at all o rings definitely look smaller and not plump. All 4 are bad. Never seen this happen before. This Q16 stuff is nasty.

the o ring problem is new to me .I figured he just over adjusted it and no more contact with the adj nut. If one of the O-rings on the float valve body is damaged then it will overfill the bowls. Gus Where are these o rings that you are talking about? Are you taking needle and seat o ring? Yeah I have seen these leak before.
