i recently purchased a nice old aead-200le. after a little tlc, the motor runs great, puts out 120v at the the front 60hz outlets when checked with my hertz meter, but it seems to jump to 108hz or so once and awhile. On another note it idles up when the auto idle switch is thrown, but never idles back down. i have read some similar posts on here but haven't quite gotten it figured out yet, i have the owners manual but no technical manual yet.

thanks in advance for any suggestions.
