I played with the float for about an hour, seems to be in the right position now. I do notice an improvement in performance now, but it still has a minor hesitation when I put the pedal to the metal. I put the vacuum gauge on again and I get the highest vacuum reading at about one half turn out. I am going to change out the spark plugs when my new spark plug tubes arrive from Australia. If I were a machinist I would make about a 100 or so for all of us slanters to use. My car has a baby oil drip coming from the number 6. Probably because someone at one time thought they should leave the washer on the plug.
