I have a 28" troy bilt storm tracker snow blower with a 9.5hp tecumseh engine. It is 15 years old. I maintain it perfectly and treat all my 93 octane gas in OPE with Star Tron. Yearly oil changes with M1 5w-30.
During recent use it has been dying under load. I completely disassembled the carb and it was pristine clean. Not a speck of visible dirt. Float needed very small adjustment to bring it to exact level. The carb disassembly had no effect on the problem. It seems to happen after it has been idling. Both times this has happened in the following sequence of events.
I start the machine and use it for 20 minutes or more with no problems. Then I leave it idle for another 20 minutes or so while I go operate other machinery. I then begin using the machine again and after a minute or so it begins to die under load. If I shut the throttle down quickly to idle it will recover and idle without stalling. But returning to full throttle and put under load will cause it to stall.
Any ideas? Thanks in advance.
