"Its a Sears aircooled 3.5 hp
"Its a Sears aircooled 3.5 hp outboard. Thanks to you guys I got the info on it - 1980, made by Tecumseh. The guy that sold it to me said the gas/oil mix was 16:1 - way off the information I got here that said 50:1. I talked to someone who said make it 40:1 just to be safe. The problem has been that I've been fiddling with the gas mixture screw, was running decent for a little while but hard finding the right setting.
Lately it starts and runs but will stall as soon as I increase the throttle. I don't know what I'm doing so called a boat shop and they said they don't deal with aircooled motors as people put the wrong oil in and mess them up. The motor is kind of a PITA as its only got one forward gear so your moving as soon as you get it going. Now I'm also noticing an oil leak underneath the cylinder I think where the grooves are and it goes all the way down the shaft to where the top of the "wings" (?) are.
It always starts and idles, and I wonder if its worth fixing. I paid $250 for it and I'm beginning to wonder if I got ripped off or I should work with it. Any advice appreciated,thanks..."
