i have a 1993 Johnson VRO 70hp 2 stroke that I've finally got running top notch. Bought a new boat project and planned to move the motor to it. New boat has an in the floor fuel tank with the fill cap located horizontally. Not real excited to have to add oil before pumping gas and hoping that I got the mixture right. The engine has an oil injection pump as part of the fuel pump but is capped at the fuel intake port. Original owner said his machanic didn't trust oil injection. I'm toying with the idea of hooking it back up to make filling up easier. Currently using a top side tank so premix is no biggie.
