Have a Webra 32 in my Outlaw with mouse can pipe APC 8x7 prop. Cool Power 10% fuel OS#8 plug. Engine ran good but would burn glow plugs after a couple of flights (I thought it was due to the 10%nitro ). Plane stored 18 months while we moved and built a home. Dispite the motor being well lubed she was gummed up and would not run. So took it apart and cleaned it well and replaced all the O rings and placed a .2mm shim to decrease compression. Since Horizon shorted me the O ring to the high end needle. I just got a new needle with the O ring on it.

Got her on the stand today Same 10% fuel, Prop tried an OS#3 plug as I thought a colder plug would hold up better. Set the needles per Webra both high and low needles out 2.5 turns. The engine wouldn't start. Seemed like it was flooding and it was. Changed to a Fox Miracle plug Leaning the high needle got the engine running rough 4 cycle about one turn out. Leaning the engine and it was just "getting on the pipe" when I completely screwed in the needle. Still ran with lots of smoke and not overheating. I believe one or two more clicks lean and she would have been fine if I could have. Didn't touch the low end and check idle as I want to settle this issue first.

Is the spraybar bad???? Ideas?
