Engine runs smooth "til mower is engaged then is sputtersand pops. After 20- 25 min. Engine stops. Copius amounts of smoke while running(darknot white).. Just had valves adjustednew plug new gas filter new air filter tune up. It runs the same as it did befor we took it in to get repaired. Mech thought it might be coilbut opted to check valves etc. Said ther was a lot of gas sittting on the piston head. Any ideas?could it be the carb is running too rich? It's 5 yrs. Old and has mowed hundreds of acresdry land farm dustyetc. Thanx in advance tmc

Is the choke staying on perhaps? check spark and plug check airflow, get compression test maybe the oil/compression rings giving way... sounds like its getting hot and increasing fuel flow for some reason??? perhaps clean carb with some cleaner while running (remove air cleaner) spray directly into carby while running run at full throttle as you spray it will try and die ... relax on the spraying and see how it goes.. check air cleaner for blockages as the same time :) hope you get it working!

SOURCE: oil in air breather
sounds like you have too much oil in the engine (should normally be around 500-600ml when there is too much oil, it gets past the piston rings and pushes it through to the head.

The starter may need shims between the engine and starter to permit the relative gears to release. Compare the two starters, if you still have the old one, for shaft length and bendix construction. Hope this helps!

Testimonial: "drallim, Everything checks out, cannot believe I've received 2 bad solenoids from NAPA. I had bought a new one and exchanged it because it seemed the switch was sticking. Still have not solved problem. Thank you for your time and efforts. Tim"
