Some have them some do not- some carbs had bowl vent that vented to that area, the welch plug was to simply block fuel sloshing out, others had that well there but never had the vent hole drilled so they didn't use welch plug.
So I had a spare one in my mess that fit and I put it on, tapped it with a ball peen and it is secure. Put carb back together and it fired up and ran fine. turned it off and I notice fuel leaking around carb. So I figured carb kit was necessary. Replaced the needle & seat, bowl gasket and bowl nut gasket. Ran the blower this AM in the snow and it worked fine. Did not notice any fuel around bowl....until I turned it off and back in the garage. I then realized where the fuel was coming from. There is a hole (manufactured) in the base/bottom of the carb throat that is just behind the choke control rod. Fuel stopped running out when I turned the fuel line shut off.
Your float needle is not seating correctly, that or your float is not .. floating...
Is it possible that the welch plug was not required for this carb? And possibly creating a vacuum or by pass for the fuel to run out that hole? I have been trying to find diagrams or kits that show all parts for the carb but can't find anything detailed enough. Or is my carb not clean enough and there is a blockage somewhere?
Thanks.
Not clean enough of you didn't put in the float seat correctly. You install with the groove in seat (hard to see on some) facing away from float needle, and has to be installed squarely and completely into the recess, viton seat can also have a crack or cut that leaks past float needle. That or float isn't able to float.
