So I was reading through my previous post about oil ratios and for motors that are water cooled you use the TCW-3 type oil. Air cooled you can use the stuff you put in your weed whacker regular 2-stroke oil.
My question is this: How can you tell if you have a "water cooled" or "Air cooled" type of motor.
I ask because I have a 1949 champion 7.5 that I think is air cooled but I accquired a 1983 Sears "Ted Williams" Gamefisher 9.9 that I have NO idea as I have not had it out on the water yet have just been Tuning it up to make it smooth running.
The second question: Does it hurt to run the TCW-3 oil in an air cooled motor just to be on the safe side?
It would have a lower combustion limit based on the other info I read in some of the postings, so being that would it create less buildup of carbon and such in any 2-stroke engine?
