| Subject: | Re: Bing 64 problems |
Bob,
Thank you, these pictures are great, and I solved the problem. 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
