Ok, so I Used the wrong words to explain. The engine would not throttle up from idle it would merely die. The reason is because it was LEAN. Not just for me but a friends evolution 58 engine also. I am at 5300 ft MSL that might have something to do with it, but still one whole turn is a long way from factory settings. The problem is not the needles it is the ignition. I sent it back to Horizon and they are going to replace it. They agreed it is faulty.

The problem is that they are out of stock until mid December. So since they had some ignitions in stock for one week in Mid September, but one week later they are already out of stock until Mid December there must be a problem. My reason for the post is to simply to see why did they run out of stock so fast? Did they order only a few ignitions for replacement parts?, is there a rash of people crashing their planes and breaking ignitions?, Or could it possibly be that people are having trouble with their ignitions and they are having to replace them (like what happened to me). Or finally did they send all the replacement ignitions back because there was a programming problem?

For the record My point is not to bash the Evolution engine. It is one of the best, most powerful engines I have seen. I would buy another in a minute I am just not sure about the ignition. I like Ralph's idea of getting a CH ignition. I might Check into that.
