||This tractor has a briggs and stratton 23 hp motor. After cutting grass for 1 and 1/2 hrs, it seems to choke down like it is running out of fuel . The tank is Half full when this occurrs. I have replaced the fuel filter,air filter and checked the cooling fins and it still acts up. Any suggestions?
||Replace the gas cap... the vent is clogged.
||I am having a smiliar problem, but in addition, the tractor seems low on power when mowing. My L120 is on its 3rd year. I also had purchase the maintenance problem and had it on maintenance for the last two years. Any ideas?
||Same problem. Found out it was the take up hose inside the gas tank. It has finally come unscrewed and fell out. The engince started sucking air instead of gas. Mine has fallen into the gas tank and I'm trying to figure out how to screw it back it. Very poor design since it's very very hard to get it screwed back into the top of the gas tank. You might try taking the gas cap off and by using a wrench/reach into the gas tank and screw it back in tight again.
