Need help with edelbrock 1406 carb

Dmopower,
Post #26. The more you post on this, the more you show lack of knowledge:
- fuel level can rise [ seep ] for other reasons than trash. Improperly machined fuel inlet seat, deformed needle, needle a sloppy fit, excess pressure & leaking gasket can all cause the problem.
- for the purposes of the engine in question, & I am assuming a mech engine driven fuel pump, the problem with a 12 psi pump is the pump, not a regulator reqd to fix a faulty pump.
- no, the tangs do not bend on the floats from excess pressure. The fuel level simply rises...& the carb floods. Once the fuel rises above the float, you now have the weight of the fuel pushing DOWN on top of the float as a counter forc

If you are correct and you aren,t when you add a regulator the floats will not need readjusted. Why would a float still seep on anew carb. Well I looked and there was no trash. I googled the issue and found several people having this issue. Under high pressure and some of the new pumps are pushing 12 psi it not only floods the carb it BENDS the float tabs. I'm shocked that just because you have not had this issue that you ASSUME nobody else has ever had this issue. Pretty arrogant.

On some of these carbs the float tabs get bent from the excessive pressure and you MUST reset the float after installing a regulator. Maybe on a race car with a cam people don't realize it. On a car that runs like FI it's pretty noticeable and an easy fix. I have never blown a head gasket but it would be ignorant and arrogant of me so suggest it does not happen.

100%. I've witnessed exactly what you're describing with fuel pressure bending the float tabs. Huge issue with the Carter carbs in the Jeep world. 4 psi max. The fuel filter controls pressure, and nobody checks fuel pressure after they replace it. 6 PSI, and the carb won't last a month. So people think the carb needs to be rebuilt, still don't check fuel pressure, and happens again less than a month. Then they blame the carb say it's junk. So they buy a new carb, and then decide that now fuel pressure matters. Lol if fuel pressure is high you can drill out the orifice to control it, but nobody does that either. They had a second regulator, and that's how they control pressure. Drives me nuts. But anyway yes you are absolutely correct
