One of the more common questions we get concerns either the overwhelming smell of gas coming from the carburetor or fuel leaking out of the bowl or overflow. Both conditions are typically caused by a stuck or worn float needle valve. The float needle valve is responsible for regulating the flow of fuel into the float bowl.

Leaking when it's not straight up sounds like BS. You should be able to lean it over to at least 45° and the float should still seal it with the needle if it is new/properly working. Andy would probably say "this 'place' you took it to, was it a taco stand?"

However, since the float height was set too high, it will continue to admit fuel into the carburetor. Additionally, the excess fuel may find its way into the engine through the carburetor jets, where it could leak past the piston and into the engine oil. The combination of fuel and oil results in a thinned mixture that reduces the oil's ability to lubricate the engine, causing premature engine wear and failure, if left unchecked.

Run the motor for 10-15min and sure enough it starts leaking thru the vent hose again 1-2min after shutdown. Not nearly as bad as the old carb but enough to make a 3" stain on the floor. When it does vent it is only a drip every 20-30sec.
