I just installed a new manifold in my 1952 John Deere 60. It now will only start and run on full choke and runs very fast no matter where the speed lever is placed. Any ideas re: how to correct?
With the engine running, spray carb cleaner around the manifold.
If the RPMs pick up, you've located your air leak.
Carb choke & throttle pivots/bushings can be leak points, too.
