I took off carb. Because it flooded over when I put a little gas in tank it must have just been a a speck of dirt not run in70 years! carb looks like new. It had to be apart before chisel marks on nut. my question should ther be a gasket on bowl and under nut? Is cork float original? Why soldered on float hinge? Got good spark good compression getting close to try arm on starting a T!

There were paper gaskets in both places originally. You need to take the center of the Model G carb apart to see if the fuel tube is there, not broken, and not plugged.

Paul -- You're right, that carb looks like new inside! Take it further apart as Royce suggests, just to be sure everything is in there that's supposed to be. Post pictures of what's in there if you're unsure. That float needle looks like new too. Most of them have a groove worn in them from use, making them work ineffectively. The cork float looks great, but some folks say that today's gas with ethanol will dissolve the shellac coating on it. Probably should stay away from ethanol if you have local sources for straight gasoline.

The vendors sell replacement floats made of some sort of "composition" material. They work fine, but you'll need to use your hinge with it. I'd run it as is until it starts messing up. Yes, there is a gasket at the top edge of the bowl, and one inside the bowl where the nut is, not outside next to the nut.

The Holley G's are good carbs. Gitcha some carb cleaner, and a gasket kit from one of the vendors, and git after it!

thank Royce and Mike I will order a gasket kit and take it apart all the way. I plan to use 100 LL av gas I get at airport was 4.00 a gal. + tax 2 weeks ago. I use it in old motor cycles we have and chain saw. it evaporates pretty fast. but it never spoils and it has lead. you have to tell them it is for an airplane.

Might consider purchasing non-ethanol from your local farm store - no need for high octane in a Model T !

Be gentle with the venturi. New ones cost $27.

You may want to coat that cork float with POR-15, or a gas tank sealer to keep it from absorbing this modern gasohol we can't seem to avoid.
