Common causes of leaking carb?

[Jim Carswell]

When I turn on my fuel valve gas starts leaking out from somewhere behind the carb, tractor doesn't start. Before I start taking it apart is there anything I should be looking for specifically? It sat outside all summer - maybe the gaskets/seals dried up?

TIA,
Jim

Fuel leaking from the carburetor when the fuel valve is opened is usually caused by failure of the float valve system. This can be a sticking, or damaged float assembly, loose float valve seat, damaged float valve needle, dirt in the float valve, etc.

You say carb leaks from behind sounds like a bad or dried up carb gasket. But also as Dean said and may have a float sticking and since it sat a long time maybe ever very rusty in side which will cause odd problems

Take it apart it needs service at this point anyway, 5 mins time and ya should have a idea.
