I have a '52 8n with side mount distributor. I located my non-start problem to be a camshaft gear with broken multiple teeth 180* opposite each other. The gear teeth appear to be a densely fiber material that is probably plasticized. I've been told this was done to reduce engine noise but I feel it may have been a built in safety factor to reduce chance of engine damage from gears. I have removed the gear and plan on rehabbing the governor as well as I suspect it may have contributed to the failing of the gear with improper RPM's?
Any thoughts on how to proceed before I start putting things together would be appreciated. I can get both the crankshaft and camshaft to turn manually so I don't suspect anything is seized internally.
