Sorry me again. Having completely rebuilt my gold star and got it started and running I am seeing a large oil leak which seems to come from the primary drive casing. I drained all the oil from the primary drive and ran the engine for a while but after some time I found the primary drive had lots of oil in again which was spilling out of the casing around the gearbox shaft.
I am told The is an oil relief in the centre of the crankshaft and this may be the source of my problem?
Any suggestions?
