2022 summit expert, I did the deal where it fogs the engine before summer. Started it up tonight and backfires and don't run to good. Basically probably just needs new plugs which isn't big deal, I have some. Question is do you usually put new plugs in every year, or was there another procedure I was supposed to follow on 1st start of the year? Want to make sure it isn't stuck in some mode where it's pushing extra oil.
