    Our Avenger sat for a few years. The engine would not hold an idle and backfired a bit (not much though). A cleaning of the tank, along with SeaFoam additive, solved this.
    I do know the Avenger you bought sat a Mavsigvik for a few years, then sat outside the hospital a few more. Maybe dirty tank? Varnish crud? Unsure though.
    Maybe it hates you.
