I am still unable to start my 9-99. Today after removing the engine from the model I adjusted the mixture control according to the Pegasus manual. I can blow air thru the carb with the mixture screw out 2 turns with the throttle set low. My ignition system appears to be working. If I remove plug it lights up when held against the engine. Turning the engine over with a large electric starter I get fuel blowing out of the exhaust. If I turn the prop by hand I can feel several "bumps" like a glow plug is igniting some fuel, but no start. I adjusted the valves at the end of last season before putting the model away Over the winter I installed the the Pegasus carb. I have yet to test the fuel which I mixed last season 1/2 methanol and 1/2 Wildcat 15% I am using on board glo with a 5000 MA battery supplemented by 5000 MA booster. The model a Ziroli 87 inch Stearman flew very well last year with the original carb Any thoughts?.
