Valve versus needle and seat?

[SmokinBBC]

Bought a rebuild kit from Tomco industries for my 70 quadrajet.

Instead of the normal needle and seat it came with a seat that has an integrated valve in it. The float pushes on a button on top of the seat shich then closes the valve in the seat.

Looks like it could be a better option than the old needle/seat. Anyone ever tried one of these? The packaging says it is a replacement for the needle/seat solution.

I sent an email to Lars to see what his experience has been.

Lars said to throw it in the trash and get a real needle and seat. He also said to throw the whole Tomco carb kit in the trash......nothing but junk:crylol:
