I could be wrong but that does not look like the correct gasket. The rectangular cutouts around perimeter of the primary venturi's should not be there. Should be soild there. you will get some bubbles there unless you are holding seat down lightly. I must leave computer for a while but if others do not provide gasket info that I might have wrong I will get out my box of gaskets when I get back. About 1.5 hr.. mds...

when I lifted the float up a little, the needle was dangeling from it but fell off and back down in the seat. it has a tiny wire on it but I'm not sure how it holds it, I dont know if this may be a problem I had or one I just created.. the pointed tip looks ok, no ring worn it and it looks clean down in the seat

Pete it is dripping off that plug on the bottom but its wet and running down from higher up.. the top arrow is pointing to the wet part that I can see but cant tell anything. With the carb sitting on a block of wood with gas in the bowl it seems like its still dripping underneath.. how would gas get out of the bowl just sitting there with no pressure on it.

If you filled the bowl up with fuel, you probably have overfilled it. This would lift the float up and the needle out of the seat with it. You will be getting bubbles, since you aren't shutting the fuel flow off.
Dump all of the fuel out of it. Hold the float by the pin, flip it upside down and blow through the inlet and see if it shuts off. You are gonna have to get the needle hooked back on the float before you do this, though...

If it turn out to be well plugs, I don't use epoxy it does not last long. Instead I use aircraft fuel tank sealer it will hold up for many many years in that enviroment.

ok Nick I see what your sayin and yes I think that may be what I did.. I cant tell from looking, how gas would leak out where its leaking, it looks like out that tube would be the only place it could go. it seems to be dripping just sittin there on the bench with gas in the bowl.

There are a couple of holes in the mid section of the carburetor (the bowl). Since it has been overflowing, there would be fuel down there. It tends to go everywhere.
Since you are worried about those plugs, pull the base off and use a hammer to gently flatten the malleable plugs down. Just lightly tap them. It is hard to get them sealed using epoxy if the bowl is not completely clean.

if your talking about the plugs seen at the very bottom, no I am not worried about them. I could see the gas trickle from up in there higher, where the upper arrow is pointed.. then it was running down dripping off that plug. When its on the engine you dont see a drop anywhere on top off the carb or looking down into the front barrels, but its pouring into the cylinder bad.

Also, the needle hanger is on the wrong side. It needs to be hung from the side nearest the float as below....
I know you said it fell off earlier while you were playing with it. If it came from the rebuilder like that, it would indeed flood, as that puts the needle in a bind inside the seat.

Yep it was hanging there as you see in the pic and soon as I moved the float a little it fell off. In the manual pic it looks like the hook comes up through the slot and goes over the float side edge?

Do me a favor, Pat. Pour the fuel out of the bowl. Maybe get a rag and pat things down to dry it up in the bowl area.
Take me another picture or two, trying to get a little better look at the areas indicated below....It kinda looks like you are using a celphone camera. If you have a better camera, I would appreciate you using it. If not, try to steady you hand a bit.

OK, I really don't have any constructive advise for you directly concerning your problem, but I just want to offer a little encouragement. You are probably feeling like you are in WAY over your head here, but don't worry! Just keep track of the parts you remove, take pictures to refer to later on while re-assembling, and take written notes, too. Carburators look really complicated, with all their weird looking tiny little parts, but it is just a machine, there isn't any "little twinkling of magic". Automatic transmissions, on the other hand, DO have a "little twinkling of magic", I am convinced of it!!
You think a carburator is complicated, take an automatic transmission apart some day!!! Hang in there, you will be just fine.

Set the float height so the top of the float is .5 inch from the top of the bowl, put the hanger on correct side as mentioned, put it back together and give it a try. If the float is not set correctly, gas can come from all over the place.
Also, make sure there is a spring behind your filter. I have seen that make a difference as well, though I do not know why.
