This "antique-auto-brass-carburetor-carb-zenith-04-T-manifold" that is on ebay is not for a T. It is off a teens Chevy 490.
It's not mine and this is free info so take it for what you paid for it.
Thank you Stan for the heads up for those that may be looking.
Stan, how about some free carb info on how to stop those new genuine original style needle valves from leaking?
I made a set for my valve grinder to regrind the tips. If you look back through the threads from the past I posted some photos of how rough the new ones are. They are being cut on a lathe instead of being ground like they should be. So I made a setup to grind them in my SnapOn valve machine. Then I polish them in my Unimat lathe with a very fine India stone and good honing oil. Then I install it in the seat and give it a good smack with a lbbfh. Then I screw it into a holder I made, suck on it to see if it will hold vacuum. If it will I put a little spring on it to hold it tight in the seat (about the pressure the float puts on it), put it under water and blow high pressure air through it. If it holds I use it, if it doesn't I say several choice words and do it again. Works for me.
James; I use valve lapping compound and "lap" the needle and seat works and is worth the effort
