hi many thanks for the info. i bought the engine as is. it has good compression. a very good spark . but the engine oil has gone emulsified. due to water in it. its also running out of a small drain type hole at the bottom of the leg. and also the gearbox oil is contaminated at the bottom of the leg.
many thanks tony. soon to be lobstering on the isle of skye scotland.

water where? engine or lower part. If engine:
leaking cylinderhead gasket due to overheating,
water flown back from wrong storage of careless flushing of cooling system or the engine has been under water.
replace engine oil, check the sparkplugs with ohmmeter and on sparks, get the engine running and see what happens and see what happens
