I simply had the enrichener disk 180 degrees off. The engine ran fine as soon as I turned it around, which was easy. Now, I have the plane flying again, but I notice my max RPM is down about 200 or 300 RPM. No change in prop pitch or anything else. According to all the charts I am probably running a little rich at my altitude, so I am going to re-jet the main, and maybe change the position of the jet needle. I don't know why the rebuilt carb would be different if all the jets are the same! Jack On Feb 3, 2008 7:09 PM, Robert Borger wrote: > > Jack, > > Go to build web site (URL in the signature block).
