I always clean the carburetors myself in my cleaner, and in this case the bowl gasket was not damaged or disturbed. It fit perfectly in the channels upon reassembly. Neither did the ultrasonic cleaning improve nor make the symptoms worse than before. I’m very meticulous when it comes to...

Not real sure how to test the crankcase vent to see if it’s clear or plugged. Also, I’m guessing that if there was blow-by, the oil would cause a different residue on the plugs than black, powdery soot, perhaps even fouling the plugs. There has been no sign of oil burning whatsoever to this...

Actually, I have not checked the crankcase breather. Could you please expound on that a bit? Thanks!

Yeah, not sure if I mis-read the hour meter or typed in too many zeros, but I know that mower has mowed two acres for many, many years. I’ll have to re-check the hour meter and verify the actual reading. So it may or may not qualify for the Hall of Fame. 🤔

Absolutely did that. As a matter of fact, right after reinstalling the carb after cleaning, I left the air filter off. Runs the same with or without the air filter.

Well, because of my suspicions that the gas was making its way into the oil, the first thing I did was remove the carburetor, strip it down, and put it in my ultrasonic cleaner for two hours at about 160 degrees. Needle and seat were extremely clean when done, so there’s no crud. I searched the...

That was my suspicion when my brother explained the symptoms from the get-go, and I changed the oil anyway just in case that was the issue. Oil level then was just slightly over the full mark. I just checked the oil level, and it’s a little below the full mark, and just smells like pure oil, so...

I have my mom’s JD GX 335, with a Kawasaki engine, 8100 hours, (FH601V-CS04, ENO FH601VB29323), and trying to troubleshoot the rough running and excessive black smoke pouring from the exhaust. My brother was mowing my mom’s yard, and after about 20 minutes of mowing, all of a sudden he...
