I purchased a used Wild Hare Extra from a friend and it flew 30 times without a problem. Today I went out and the engine sounded and ran terrible. I could not fly ineverted at all and it seemed to be running hot. Temp after a 5 minute flight was 238 were the plug goes into the engine and 220-240 on the middle of the cylinder. Is this too hot? Some have said yes, and some have said no. I took the plug out to see the condition, and the electrode was white indicating lean, I think. So I tried richening up the high side and no change in running or temp. I then richened up the low side and the idle became very erratic, sounded like a car with a surge problem. This is strange becuase it has flown so well. I am going to get a new plug but I am lost. Then I set both mixture screws back to were they were when it was flying good and the thing will barely idle. Any ideas??? I kind of got frustrated and just gave up for today, but I really enjoy flying this bird so I want to get back in the air but it stinks to think that every time I pull the throttle back it could be a deadstick. Oh yeah the problem seemed to be really evident at idle and at half throttle. It is a BME 50 and I think it is approximately 2 years old.
