just bought 1991 safari L electro,,7 years ago it was put away for storage and someone poured engine oil down cylinders,bled out oil system then from filter to carburators primed with engine oil as well..my question is 1.) how do i now re-prime and fill system with proper injection oil,,2.)how do i test engine seals on both sides..also did compression test and had 190LB in each cylinder..seems a little high perhaps?
