Hello, I have a Toro Timecutter 4235 that dies after it warms up (about 20 minutes). After it would warm up, it would start dying. If I shut the blades off and idle quick enough, it would start running smooth again 30 seconds or more later. Then run full throttle and cut grass for about 2 minutes and have to do the same thing again. Apparently after the tractor warms up, it starts to drink gas faster. I took off the covering around the gas tank. On top of the tank, the fuel line goes thru a metal elbow and then has a hose going to the bottom of the tank. I blew out the elbow with compressed air and a bunch of tiny bits came out. Before I blue it out, it was hard to blow thru. So that fixed my issues. I also notice I had little bits of grass in my tank that I had to clean out. I emptied my tank thru a filter to save the gas. All good now! I had this problem for like a year plus. I changed plugs, fuel and air filters. Figured I must share!
Note: This problem is resolved. Just wanted to share.
