This poor neglected Jeep (Muffin) had sat for over 3 years. Added 5 gallons of fresh gas and a bottle of Marvel Mystery Oil to the tank, changed the oil, and put 4 oz of Rislone in each cylinder to free possibly stuck rings and lube the upper cylinders, hence the smoke screen. There might be a “slight” exhaust leak too.
Removed 3 wasp nests, without getting stung! Also removed about 5 pounds of dirt dobber nests. Used an entire bottle of Simple Green and half a roll of Blue Shop Towels to clean the interior, all kinds of critters had been living in it.
