Oil/Gas Mixture: Manual says 24 to 1, not 50 to 1???

[ka3wld]

Hello all, Well now we have a 7.5HP Ted Williams (still looking for the year). We got it for a song and she runs well. Manual that came with it says 24 to 1 fuel ratio. I know I saw a similar post somewhere but I think if I did a search on oil/gas ratio, I'd be looking through all 30 plus posts What should we use? Thanks in advance

Howdy, Ka3. Lots of people run those oldies on 50:1, but there is no guarantee that will be a good idea. I run 50:1 in my 1948 Sea King, but I crank that oldie up only for demo purposes and almost never load it up.<br /><br />Try mixing some 36:1 (6gal/1.5 pints) and run her on that. If that works try a little 50:1. Monitor temp closely.<br /><br />TC-W3 is much better than oils were in the 50s and 60s. It is just a question of how much better and how loose is your old engine?<br /><br />Red sky at night. . . <br />JB

Hi J.B., Isn't 50 to 1 = 1 pint to 6 gallons?<br />I'm confused now and math isn't my best subject Well now at least we have two back-ups. A 50LB thrust TM and this oldie Oh does anyone have a diagram on how to make a motor bracket for this kicker? Thanks so much. Glad your vacation went well JB <br />(wa3ipb's wifey)

ON THE OLDER ENGINE THE ROD IS SETUP FOR <br />25 TO 1.<br />YOU CAN RUN 50 TO 1 BUT IF YOU STICK A PISTON<br />OR THE ROD CAMES OUT.<br />I WOULD SAY 37 TO 1 WOULD BE OK BUT IF IT WAS<br />ME WHAT DOES THE "MANUAL" SAY.<br />
