Magnum xls 46 new engine
Hey guys
I broke in the engine ,I ran 2-3 tanks of 10% fuel and just followed the manufactures
directions ok, Then I took the plane flying The manufacturer say now fly the plane and
very slowly lean a 1/8 turn per flight and you will be done. After 3 flights, I took off for the fourth
and it bogged down on take off. so I landed fast and richened it up a bit and then it started
surging That now is my problem, it seems as now matter where I set the high speed neddle
it surges at full rpm it will surge up a 1000+ rpm and then it will drop a 1000 or so. up and down
What causes this surge. I have tried 1-3/4 to 4 turns out on the high speed neddle
and all I get it surging
thanks David
