B&S V-twin on Zero turn mower.
This all started when the engine failed to start one day, had been running great and starting easily after I found out how the intake valves should be set to activate the compression release. Before I did that i would have to turn it past compression by hand for the starter to spin it.
Pulled carb, was spotless, couldn't find anything wrong with carb, put it back on and it ran great...once. Bought a chinese one on Amazon, put it on ran great for months. Then gas started dripping on muffler heat shield. First thought was fuel hose at tight bend, replaced. Stil leaks. Appeared to be solenoid threads. Tightened, stopped for a while (2 weeks). Leak returned. Removed solenoid and used teflon tape. Leaking but not there. Removed cowl and air filter and ran it. Looked like the gas was coming from top cover gasket. Replaced. Leaks...Removed the fuel pump pulse tube and fuel line and finally saw bubbles coming from the carb inlet metal tube. Dang thing is just a press fit-no o-ring or anything. I didn't think permatex would last so I used JB weld. Was careful not to plug anything up. hope this will last.
