Well to be totally honest I didn't see oil on the dipstick, I just decided to drain the oil and change it and filter, just for the off fact that it might have been like my generator that it had a low oil level shut off. You may have two problems but this will let you test for the type of smoke you are getting and why, blue smoke or black soot flooding smoke.ĪND some of them carbs just have a rubber tip needle and a brass seat and you can clean the seat with a Q tip.ĪND you need a Briggs type WHITE 60 micron inline fuel filter before the carb and I would probably install a in-line fuel shutoff before the fuel pump as additional oil sump flooding protection. You can generally find replacement vac type fuel pump W/O going to JD counter and getting bent over backwards and forwards and molested.:tango_face_wink: If gas gets in the oil sump and the gas tank is lower than the carb and engine, gas was probably being pulled (sucked) into the engine by a bad vac/pulse type fuel pump when the engine is running. Get a little gas tank and some fuel line and elevate the gas tank higher than the carb/engine and connect directly to the carb so as you have gravity gas flow to the engine carb, start your engine and if it's still smoking and it's black soot your carb is flooding, if it's blue oil smoke let it run for awhile and if keeps on smoking you may have bad head gasket leaking through internally, but this will not cause gas in the oil sump, just blue smoke. I always put a fuel line shutoff on all engines that use that type carb when the gs tank is higher than the engine because I've seen those type carbs needle/seat fail and intermittently leak through when at rest and flood the crankcase with gas but the engine run ok when in use because the leakage is just a slow seep through the needle/seat.Ĭompletely disconnect the existing gas lines from your fuel pump. (and it's common for the pintle to become sticky either way in or out. If the pintle was stuck extended out the engine would starve for fuel under load or not rev up. I've actually removed the solenoid and cut off the pintle so as I could use the carb on other engines that did not have 12v power for the solenoid. If you took the wire off the anti-backfire and the engine runs for long time at full throttle the little needle plunger is stuck on the solenoid and is not anything to be concerned about other than the engine can backfire when dying. Summary: the anti-backfire solenoid is not a total fuel shutoff. If the gas tank and carb is higher than engine manifold and the needle seat in the carb is leaks with the engine at rest the gas will go into the oil sump. The little solenoid on the bottom of the carb bowl will not completely shut off the gas flow through the carb as some believe, it just severely restricts the High speed jet fuel flow to keep the engine from backfiring when the key is turned off and the governor then kicks the throttle wide open which results in a backfire if the engine is sucking gas through the H jet area.
