Am in the process of rebuilding my 90 hp 3 cyl, 1995 chrysler/merc/force motor. Most posts I/ve read say one should use a 24/1 mixture gas to oil. My engine has a oil pump and auto mixer, so how do I go about getting a more oil heavy mixture for the break in period? Also are there any adjustments on the little oil pump that will increase the amount of oil mixing with the gas? Thanks, todapark
