things to check…
Compression FIRST !!! in case the engine is RIP before you spend $$$$$$ to refurbish… publish findings here!
- Ignition coils…. usually all cracked up and need replacement.. not a big deal
- ignition wires… usually old in need of resh new 7mm copper strand wires ( no carbon stuff)
- condensers… usually gone bad after all these years. can be tested but…you need capacitance meter yet they can only be truly tested using a hight voltage source …see links provided below
- Gear case oil needs inspection and replacement ( look for water ) use new nylon washers when closing up
- Points… usually a clean up will get you going (polish with 150 grit strip of paper and rinse with carb cleaner
- suggest you get familiar if all this stuff is new to you (see Johnson manual) see Leroys section on magnetos etc…carbs
