I am new to this website but I posted a question and within a day had an answer. I am sure that I speak for all of us who do not know a lot about boat motors that we really appreciate the time and energy that those of you who do know these answers spend on this website informing us. Thanks..
Have recently picked up a 7.5 H.P. outboard, short shaft, old Ted Williams air cooled engine. It appears to have a Tecumseh engine in it (It looks like an old lawn mower engine). Would appreciate it if anyone knows what oil/gas mixture I use and what weight of oil. Thanks
