I finished my plane in May of this year and have been working on 2 issues and seem to be getting nowhere. It's an 4 place, O-540, magneto's. I have called and talked to Bob and Mike, but I see the same things on the forum as they have told me.
1st problem is high CHT's. First flight they were pushing 500, now I have them at ~450 on climbout but once I am at cruise they come down to less than 400. I have opened the outlet several times, created a lip, created a bigger lip, moved the exhaust to the outside edge of the tunnel, gone through the baffling several times. Nothing seems to making a huge improvement. I have read that possibly it is running too lean could be an issue, and rejetting the carb would help. I have not heard of anyone doing that on this forum. I don't have a fuel flow meter so I can't tell what the fuel flow is. I have been looking through the forum looking for idea's but maybe else has something I can try before I have to redo my cowling.
2nd issue is a "Heavy" left wing. I have been through checked the horizontal levels, adjusted, flaps, adjusted, airelons adjusted a few times. Put washer's under the lower hinge of the aileron heavy wing and light wing, but has not changed much at all, some things have made it worse and some have made it better but still left wing always wants to dive to the left when letting go of the stick. As of now when I let go of the stick the right aileron falls inline with the flap and the left is raise. I reflexed them about a 1/4 inch and the left aileron goes up about 1/2" when letting go of the stick. I can take my feet of the rudder and the ball stays centered while holding the stick and then when letting go of the stick the ball goes to the right. Running out of ideas to try, I feel like I may be missing something but cannot figure it out.
I'm not sure if it would good to do all the flight testing with these problems, or just do the flight testing as is and slowly work on the issues. I have about 20hrs on the plane now.
Any ideas would be appreciated. Thanks.
