He're's the latest update:
Ran some carb cleaner through the gas tank and it's running fairly decent but it's still backfiring on occasion (only when shutting it off though.) I make sure it returns to idle before shutting it off.
I've ordered the valve adjuster wrench and the feeler gauges from the dealership. I've been busy and haven't had time to play with it, but I think I'm going to take the carb off and clean it properly then try the valve adjustment. I'll report back when that's done (won't be for awhile.)
