Old Laser (Mountfield / Westwood family, belt drive, Kohler twin engine).

Tecumseh 6 speed gearbox and back axle, had to remove it to free up
corroded selector shaft. Surprised to find it lubricated with a graphite
or moly grease, not particularly thin. Would have expected oil or at
least "CV joint" type grease. Can't find any guidance on the web, anyone
got any thoughts?

TIA....Steve
