Hey all, I need some help. I have a 1985 70-HP Johnson model number J70TLCOS that smokes badly when trolling. Is there an oil injection adjustment?

Sorry to inform you of two misconceptions:
--there is no oil injection at all on your motor
--there is no adjustment for the ratio of oil mixed with gasoline in the fuel system.
The OMC motors of that era used an oil-gasoline mixing system. The oil was just mixed into the fuel line as it was fed to the carburetors. The oil was not injected anywhere, and especially not into the combustion chamber, as the normal use of the term injector implies. If your motor has a notation of VRO on the cowling, it has the oil-mixing system.
The oil-gasoline mixing system is expertly described in an article in the REFERENCE section. Read
