I bought a primo 1960 something 3 or 3.3 hp 2 cyl outboard engine to put on my jonboat...Motor is wrapped and stored in the box,is why i dont have the exact info...This motor looks like its never been ran,very clean...Anyways my question is this...What ratio do i premix my oil to run in this when i decide to use it...Thanks...This would look awesome on a stand in someones garage that collected antique motors...![]()
