Sorry guys. I replaced the worn prop jack shaft with one machined locally out of aircraft alloy steel. I have completed replacement of all bearings and belts in the PSRU and pre-rotator systems. Lubed the PR drive shaft, and am now waiting for Sport Copter mast, hub, rotor and trim system to arrive. I have ordered upgraded fuel pumps and filters, with new 5/16 fuel lines for now in preparation for later turbo. Pressure checked the fuel tank, bore scoped the engine. I can still see cylinder cross hatch marks and all valves look "like new". New plugs of course - cheap compared to buying plugs for certificated aircraft engines.
I was unable to enlarge the eccentric hole, but got eccentric installed and am "just able" to turn the prop belt adjustment bolt with a new long handled wrench. I studied up on belt adjustment from belt factory documentation and am waiting for proper tension measurement tools to arrive this week. Then will be done with everything but the new rotors and trim system.
