[NSRCA-discussion] YS1.40FZ Prop Size for a Focus

[jivey61 at bellsouth.net]

Have you pulled the valve cover and checked the valves to see if they open and close.You may have broke spring or bent valve or cam problem. Does it have compression?

  Engine will not run. I even put some fuel in the plug hole and nada. The engine is pumping fuel and I get it flowing from the NV 

  Housing with the NV removed. New YS Plug and the fuel runs fine in my other YS. When I pulled the plug expecting to find the engine flooded no fuel came out the plug hole when spun by the starter. It'll pop and try to run once in a great while. I've removed the pipe and header to ensure nothing there was doing it. This thing ran one flight after coming back from YS. It went what I thought was lean but come to find out it was rich at 2 turns out. YS zero  Broken Landing gear 1. L

  Can you decribe the symptoms?  One issue I am aware of is a bad finish in the bore of the pump regulator. The plunger gets stuck and too much fuel gets pumped into the engine.

  Because the 1.60 is headed back to YS service yet again. One short flight after the last trip out there. I've never had problems with YS engines before this one. Spent 2 hrs yesterday trying to get it to run.

    I am changing the YS1.60 in my Focus to OFB's YS1.40FZ and was wondering if anyone had an idea what the best prop was? Using CP 30% heli fuel.

     

     

    BTW I got the landing gear as well.......  J
