I have a John Deere L120 riding mower with a 22 hp Briggs & Stratto v-twin with approx 260 hrs on it. It has been smoking & using around a 1/2 quart of oil for about the last 100 hrs. of use.Would like to know if it's a valve seal problem or do I need to re-ring it. Please email me at [email protected]. Thank you, Mike.

IF IT WAS MINE , MIKE ,I WOULD USE A HEAVIER GRADE OF OIL-----20--60 OR THERE ABOUTS PLUS PUT A SEAL SOFTENER ADDITIVE IN AS WELL,THERE ARE ANUMBER ON THE MARKET,I USE REDEX INTHIS SITUATION. THOSE TWO THINGSWILL GIVE YOU A COUPLE OF YEARS TO THINK ABOUT IT. "YOUDOIT"

I ALSO HAVE A L120 THAT HAD THE SAME PROBLEM. I TOOK DOWN THE CRANKCASE A FOUND A CARBONED UP PISTON AND RINGS. I PURCHASED A NEW CRANK CASE AND A NEW SET OF RINGS. HAVENT ASSEMBLED IT YET. ONLY HAD 300 HRS ON IT. BE SURE THE CRANKCASE HAS THE RIGHT CAMSHAFT BEARING BORE FOR YOUR EXISTING CAMSHAFT.

I have a L120 and I am having gas problems. I changed the fuel filter and the gas pump. Mower runs for a while about 5 min. then starts to die. Put choke on full and it just lets it run standing idel only for a bit then dies. Any solutions here?

Solution #2 has a pinched fuel line between fuel tank and frame.First post should do a cylinder leakdown and that would give you a very good idea on seals or rings.
