RE: Cox piston Failure
dcbdbis;
I enjoy your posts, and the info and data you are posting is very useful and welcome.
I use mostly Tee Dee based engines, but like to use Medallion carb setups, I find the runs are more consistant. I really do not see a issue with loss of power/RPM with this setup. The Needle valve/Spraybar used and looked for are pre '75 if they can be found. I feel the later ones had worn tooling with the spraybar, and feel that may be a factor to Cox dropping the Medallions from production. Perhaps you could add your thoughts, I would like to hear what you could add.
I am also interseted in hearing what you may have that you no longer have need for, parts are always needed and some are harder to find than others.
Thanks again for your information and insight!
