ORIGINAL: old n slow
Have a new Evolution 46 and I am pulling my hair out. It started on the first flip and needed no adjustment. Took off and flew for about 3 minutes and the engine died. Dead stick to a soft landing. Engine now won't run. No matter where the throttle is the engine will die when glow started is removed. Had another pilot, who know more about engines than I do, check it out and made adjustments. Still no luck. We worked on it for about 1 hour at the field and when we could get it started it would still die when glow starter was removed. Brought it home, removed and checked the tank and lines. No leaks anywhere on tank. Even checked the carb and made sure all screws were tight. Removed the high speed needle and blew out the carb and needle. Fueled up and same thing. I'm ready to put old OS back in.
Should I call Horizon for help or is there someone here who can assist me. Being a senior citizen I am at my wits end, I only have 1/2 a wit as it is. [sm=bananahead.gif]
Thanks for any assist.

Old and Slow, you and I have a lot in common.
It sounds as though the engine was too lean and damaged the glow plug. You really need to adjust a two-stroke (AND four-stroke) glow engine every time you fire it up for the first time in a day. Why? To prevent just what you are going through right now.
Unfortunately, our engines will run when they are a tad too lean. This reduces the engine's useful life time and can be a glow plug killer.
Never believe anyone when they say that you don't need to fuss with the needle valve, especially on a two-stroke. The needle valve control our engine's ignition timing by varying the amount of fuel. More fuel means the timing gets retarded, which is a safe way to run your engines.
Replace the glow plug, turn the high speed needle open a turn or two, follow the engine's break-in instructions with the model elevated several feet up off the ground and then tell us how you made out. Good luck to you.
