I have a 1969 Action Age Scrambler 1000 model, 6x6 Amphibious vehicle with the original balloon tires that hold air in good condition.  It's a one owner machine that has seen little use since 1979.  The machine is in very good condition with the original balloon tires and  a custom cover.  In 2012 the stock motor was pulled and a 420cc 4 stroke predator motor was installed.  I still have the original motor.   The engine starts and runs, however it wont run on its own fuel, I think the diaphragm in the fuel pump is stuck from sitting.    I do have a custom exhaust pipe that needs to be assemble and installed. The stock muffler is restrictive and causes to much heat inside the engine bay.  The belt is a little tight, it holds the clutch open, so it is always in climbing gear.  Basically it needs a fuel pump, new belt and the exhaust pipe assembled and installed. I do not have time to finish, I am going back to school
