Z425 Fuel Leak

[depawl52]

So my 12 (+/-) year old Z425 began flooding when the choke was on, and leaking fuel which I eventually figured out was coming from the muffler. The next day the problem somehow resolved itself.
Seems to be running OK ever since.
Anyone have any ideas as to what the issue might have been?
Thanks.

Sounds like some sediment got in the float bowl and prevented the needle from seating and shutting off the fuel. A good carb disassembly and cleaning is likely needed.

I install a manual fuel shutoff valve in the fuel line of all my equipment, then run them dry when shutting down.

Thank you Auto Doc. I kind of figured it was a carburetor problem. I've been watching youtube videos on carb disassembly/cleaning, and although I haven't found one for this particular model, all of the Z's seem to be pretty similar.
As as side note, it appears that new carburetors on Amazon are only around $50 so I may just go that route.
Thanks again.
