I have a simplicity legacy 25hp kohler when blowing snow this morning it was running fine. about 40mins into blowing it started missing and backfiring. Pulled into the garage checked fuel fitler plugs which looked lean and oil. Added some dry gas to the tank started up and let run for about 5 mins. Pulled outside and started PTO and ran fine. Started blowing snow and only was able to blow for about 3 mins and it started missing and backfiring again. Not sure what i need to look at next.
Possible couple of things
low battery voltage by the system not charging enough
overheating component in the ignition system--coil failing when hot
engine overheating- no air flow around head and cylinder fins from dirt and rubbish
