    Plugs are new Champion J6C’s, not dropping a cylinder, just loosing RPM’s then gaining it back. I guess I could always clean and reset the points and go for another ride and see what happens. When I got this motor, I did nothing to it at all, except for impeller and t-stat. Found the issue after running it on the boat for the first time yesterday at the Thompson CT wet meet. I don’t think it’s fuel as playing with the choke has no effect as well.
