sticky power piston
I have my Q-Jet apart ready for rebuild. The power piston does not slide very smoothly in its bore. It is actually difficult to install even though the parts are very clean. How can I fix this?

Power Piston
The actual power piston is not hard to replace, but I have not seen one come with a kit. You most likely have varnish in bore or on the piston that is causing a drag. Take apart the Q-Jet and soak it in carb cleaner, including the piston. If it still binds take about 1000 grit sandpaper and lightly polish the piston wash it and put it in. It should not bind now.
