Well I’ve typed stuff out twice now and added pictures, but the site just blows it up when its uploading, so footch it, you get no images from me..
Check your upper oil seal if you haven’t already. If it leaks, you’ll see some grimy oil working its way down the side of the engine then onto the leg, usually the port side.
If the coil setting ring isn’t doing it for you, try doing it by eye and by feel, thats what I’ve been doing for forty years of playing with these things. I don’t use a setting ring because I’ve never bought one.
I have a ’57 Fastwin that was given to me because it was getting “tired” according to its owner. Losing power, spark inconsistent, etc etc. Top oil seal replaced, magneto plate refurbished, carb cleaned, new hoses on the motor and tank, rebuild kit in the tank, NGK spark plugs installed. That is all the rehab work what was done to it, and now she runs all over Lake St. Clair and doesn’t miss a beat.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
