fuel dist control piston seal replacement
After many, many hours of chasing a rich idle/cruise concern. I finally found the culprit. Has anyone changed one of these (89 560sec)? I understand I first need to measure the height setting prior to removal. I also read somewhere that there should be .06-.08 play in sensor plate before the control piston actuates. Since I reset the sensor plate (was too high) I would then need to lower the height setting on the control piston to achieve the free play.
Am I on the right path here or is it "stinky thinking"?
