I have a 1962 3 hp Evinrude Lightwin that was given to me, that I have not been able to get going. Coils and points are all new from past owner, have checked and set to manual specs. done a compresion check and to me is uneven on both cyclinders readings from 10 to 55lbs max on bottom cyclinder and 40-45 lbs on top cyclinder. Can not find anyware what compression this motor is suppose to have anybody know? Also if you remove the top plug I noticed while checking spark the motor starts on very first pull? will not do this with the bottom plug out and top plug in. Mixing gas ratio at 24:1 is this correct? Any help with these things is welcome, debateing weather worth moving forward with this motor as far as repalceing rings, rebuilding motor head and sinking more money into it or just make a boat achor out of it.
