OK I was going through the gears and boom all the sudden my blaster started running bad it was sputtering and spitting. On the way back home it started to pick up a little then I pulled into the yard and pulled in the clutch and held it at a steady rpm then I let off and it died. I thought the plug may have fouled but I checked it and its good. Now it won't start and when the kicker stops going down it quits turning over pretty quick. When I kicked it it backfired a couple times. I am away from all my tools right now so I can't dig much deeper into it. Anybody have any ideas?
