The thing to do with the float is to simply BEND the hanger a little.. What I do and do NOT advise is to hold the float hanger in place and have someone crank the engine till the float bowl fills up and then I can see where the actual level of the fuel REALLY is. If you do not do a "hands-on" while cranking the float assembly will shoot out of place and gasoline will go everywhere not to mention the parts shooting into the manifold...
There is one other thing to check in that carb. All of them I have ever seen had a small RED RUBBER valve for the pump system... You may be having a pump problem! Look closely at that while you are in there.
Also If you are doing a KIT REBUILD, the only parts I ever use are the needle/seat. the PUMP and maybe a new gasket.
If the carb was running good before suddenly going bad then only ONE thing is wrong with it and it does not need all the bits and pieces of the kit.
