O S 65 LA ldle
After about 2 hr. of breakin running time can't get engine to idle below 3500 RPM. any lower and it will start surgeing and die. I'm running 10% Wildcat fuel with 12/6 A P C prop. I get about 11500 after leaning to peak(12200) and backing off 1/2 turn. I have the 40 LA & 46 LA both have run great out of the box. I'm very dissapointed in the 65 LA. NEED HELP!!!

The first thing we'd do is replace the fuel with fresh, clean fuel...especially if it's left over from last season. We'd also install a known, good glow plug.
You may need to check the idle mixture adjustment. Start out with the air-bleed hole in the carburetor blocked 1/2-way by the adjustment screw. Turning it in richens the idle, turning it out leans the idle.
If the engine will run 'all day' when leaned to peak, then the idle should adjust easily. Leaning to peak and richening 1/2 turn may be richening too much. Try a little less and see how it goes.
