W8ye,
The actual RPM reading was 7895. I just came from the shop and checked the carb while I was there. The carb on it was a WT 215 (Walbro) with a 5/8 inch opening. It is a twin ring ryobi with a wacker muffler. I tore it down and polished the case as well as smoothed out the transfer ports. But as was mentioned, I am suspect that the problem is to big a carb. I didnt modify the reed at all. I have the original carb that was on it and it is a Zama P171ya with a 7/16 opening on the outer rim and a 9/16 opening at the butterfly. I guess I will go back to that carb for future tests when I get the plane repaired.
