I just purchased boat with this motor. Found out after the sale oil tank for oil injection is removed. Not sure why and there was no explanation. Motor looks really new and seems to have really good compression. Im thinking it would be good idea to adjust CARBs. The two upper cyls have the screw while lower two dont? 4cyl motor and was just looked at by a marine shop to have new plugs and such installed before i bought boat. Ive heard of link and sync where you get butterflys inline. Am I missing other adjustments for lower cyls? 1 and half turns out on all of them.
