24:1 for an early '70s Volvo Penta 5hp. Use TC oil rather than TC-W3 for an aircooled engine. :)

Re: Crescent/Archimedes/Volvo penta 5hp fuel/oil mix

For a 1977 5hp Volvo Penta the recommended mix was 50:1 using Volvo oil but a bit more oil when using other brands (I cant remember how much tho' as my engine and instruction book are on permanent loan...40:1 I think) No mention was made of using TC rather than TC-W oil.<br /><br />I found the thing troublesome in that it cut out (plug fouled) if left idling for long. It usually ran for long enough to get the anchor up to the stem head and then cut out!! Very frustrating when single handed. The trick was to start it, to make sure it was Ok then stop it, get the anchor up and then restart it. A spare plug and plug spanner are vital though.<br /><br />Maybe TC oil, for air cooled engines, would have been a good choice I never tried it. Also I never used Volvo oil but stuck to a 50:1 mix

I was wondering; How many ponies could you expect from a Crescent/ Archimedes rated 5 on the cowling. My Tohatsu 3 runs stronger. Btw, I use Triboron in fuel no oil, I dont't like smoke on the water.

What is triboron ???------A 2 stroke uses oil in the gas to get the LUBRICATING oil onto the internal parts.------

Say, this thread is over 17yrs old. You may want to start a new one...
