Hi;
Just received this engine back fro m YS sent in for for problem with fuel leaking out of carb.Finally got it in plane and tried it yesterday.Can't get to run consistently.On high end no matter how rich set will run then lean out and quit!On lower end seems to surge or hunt?up and down almost quits then goes again no adjustement on the idle will stop this?Pulled fuel line has ample pressure there!Just can't seem to find a spot it is happy at.Wll rev up good and seem fine then slowly taper off and quit!When inverted will still drip fuel out of carb too,that was intial problem!Using cool power 20% with some caster added,cpou;ldn't get the 20-20 I wuld usually use!Think it is cool power it is the green stuff.Any hints?
