You probably have some crud in the carb float seat, causing the overflow.
Sometimes the petcock does shut off completely, and the combination of the two can leave a puddle.

Another good argument for installing an in-line fuel filter between the tank and carburetor. Clean fuel won't clog the float needle valve. All kit tanks come with crud that needs to be filtered out even if the tank is cleaned well before installation.

The above advice will probably fix your problem unless it is being caused by a leaking float bowl gasket. If the bowl has been removed for any reason you should check that the float hinge pin was reinstalled correctly. If not it can extend into the gasket area and allow a gap that will cause a fuel leak.

Let us know what you find.

Your float might not be working properly, mine was initially installed upside-down, causing it to leak. Worth checking. And if that doesn't work, try bending the little tines that the float touches so that they're down a little more.

Not saying you're wrong here but the float is just a plastic donut. How could it be installed "upside down"? They'll work either direction they're installed.

As far as fuel/oil coming from the intake side of the carburetor; it is a piston ported 2 stroke engine. It is normal and common for them to have some blow-back through the carburetor. It isn't something to be concerned with. It's the nature of the beast.

You must have a knick in the float valve seat, or on the tip of the float valve (needle) where the fuel comes into the float bowl.
Or a really bad gasket.

Don't know who you are but if you're using different usernames you're in violation of forum rules. The original posts from a member having a similar username, Zearobiker, singular, doesn't sound like you. He can spell.

If you have recieved negative PMs you should report them to the staff and we'll take action, if needed. Since you only have one post I doubt you've recieved any private messages from other members. I'll do a search on your IP address and see if we've heard from you before.
