Hy Lode51, put a vacuum gauge on the engine and see what readings you get. Only 7 1/2 - 10" of vacuum will advance timing 7 1/2 - 10 degrees, while centrifugal advance starts at 700 engine rpm. It would seem that maybe we should be disconnecting the vacuum advance while setting the timing, even though it doesn't mention doing that in the manual. Why don't you try it and see how it runs, let us know please.
