Lawn boy carb restoration

[Burt]

I have a 30 year old lawn boy that has not been run for a dozen years. I cleaned the carburetor out and replaced the float needle and the jet that it fits in. Parts #9 & 10 on the link below.

It now runs (more or less), but when I turn it off, fuel continues to come up through the middle of carb (up the nozzle #12) and leaks all over.

Any thoughts on what is causing this? does the mean the cork float isn't floating? Or should I be screwing in the part #2 - Needle Adj. Is this needle adjustment for setting idle speed or some other purpose. very awkward place to have and idle adjustment screw because you can't move it w/o shutting the engine off and taking it partially apart.

I am more an expert on Briggs and Tecumseh than Lawn Boy, but I would think that with those cork floats, either it is saturated and to heavy to float, or it is binding somewhere. OR, there is a plugged float bowl vent . The bowl has to be vented, or they will run over. Many Many years ago I fought a tecumseh carb that just wouldn't stop running over, till I found the TINY bowl vent in the side of the body. Also jet #2 is the main high speed fuel mixture adjusting screw. Probably needs to be open about 2 turns+ or -

Is it the plastic carb? They will get hairline a crack when they get old and leak fuel. I would not worry about a cork float, I have seen them 50 years old and still fine

The float is probably not logged, but to check it just put in a
container of fuel, it should float high on the surface. Under section 4 fuel system in this link read what applies to your model:

float could be adjusted too high as well, the little tab that pushes on the needle is pretty easy to bend when trying to fumble things back together.

Epilogue: First I realized that I had switched the plumbing on the fuel line and the primer lines. Then I needed to bend the float tab. Then the main jet was still clogged. Finally got it running. Thanks.
