[R. LIPRIE]

ahh crud.  Sorry I misread what you said.  Matt is right disregard what I said,.  Take the advice from him..  I was just listening from someone at the field today who said that thing about a 160 which is what I wrote about and I'll tell him next time I see him that he was wrong and don't do it.. Sorry bud.

  Tim,
  DO NOT do what Matthew L. said with a DZ. If you do, you'll have to manually prime the engine every time, and possibly cause internal engine damage because of it running lean while running the fuel out (it could backfire and cause all kinds of damage). The reason YS recommends using the synthetic heli blends is because it is safe to leave the leftover fuel in the engine (especially the Cool Power 30% HP Heli blend). I had a similar condition with my 1.40DZ last weekend and it was caused by a tiny bit of grass holding the pump open. I'd recommend tearing down the pump assembly and giving it a thorough cleaning (replace any worn parts as well). Also, make sure you're cutting of fuel flow to the pump between flights. I know you said you have a cutoff, but if it's not used every flight this flooded condition can happen.

  Matt

    You know what what I would try Tim.  Is when you get done flying.  Defuel it and hook it back up and start the engine and go ahead and run all the gas out of it.  This is worth a try.

      OK I finally took the YS1.60 apart and when I pulled the Valve cover to check the valve train I got what looked like  a gallon of fuel out of it. So being the Master of the Obvious that I am I must have flooded it, BADLY. 

      So what are the correct starting and end of day procedures for this engine? I do have a shut off on the fuel line for between flights. Only thing I can figure out for why it quit in the air was I had it too rich at 2 turns out.

      The YS1.40FZ just doesn't have enough punch to fly the Focus with authority.

      Tim
