Have an Ariens Platinum Deluxe 24" snowblower and it runs great, as long as the choke is engaged one slot.
When the choke is off, the engine seems to run OK, but it has a sound of backfiring almost constantly and it emits light blackish smoke through the exhaust. I also noticed that when the choke is off, it makes no difference what the speed lever is set to; it won't change speed above something like idle.
I guess it's something with the carb but don't know exactly what it will take to fix the problem. Where to start?
