Supertiger 2300 Questions/Problem

[Royce Dorsett]

Thanks for the info.... If my Cline doesn't solve the problem, I will look into a 2-stoke engine...

  I havent used the CLine setup but the Perry setup definitely works especially if your tank is high or low.  The tank in my Prophecy was almost 3" higher then the carb and this was the only way I could get to work in this plane.  It would starve in the negative manuvers till I changeed to the Perry stuff.   By the time you spend on a pump and carb and not to mention the frustration of trail and error you may as well invest in a pumped engine.   $185 engine,  $45 carb, $35 pump, $45 wraparound header... total  $310.
  For about $380-$410 you can buy just about any of the 2-stroke pattern engine out there.  You can make it work though so dont get me wrong.  IF you allready have the engine this is what I have experienced.  One other note:  You will be about 2.5 oz heavier with this engine setup then most other stand pattern engines, so allow for the nose heavy-ness.
