Re: outboard storage
Fuel stabilizer is great stuff (especially the OMC brand IMHO) and should be added to the fuel. You are lucky with the 1970's model. I never had a clogged carb except the rare stuck float valve on my 6 HP which I ran in salt water without a cowling for 15 years! Upgraded to a "new" 1990 model about 4 years ago and the dang carb needs rebuilding anytime it evaporates dry, usually after sitting in Florida heat for about 6 months. Anyway, on the old 6 HP I ran the carb dry before storage and it worked fine, on the "new" one, I choke it to stall while flushing, squeeze the fuel primer bulb hard, leave the choke out, and put it in storage. This seems to work. I really wish I could fit the old 1970's carb on the 1990 motor.
