What is the oil to gas ratio for the Homelite 330 chainsaw?

Answer 1

Go with 32/1 (gas/oil). In hot conditions you might go to 16/1 to get saw to run cooler.

Improvement;

You Never run a 2-stroke engine at a higher ratio of oil. When you change the fuel/oil ratio, you also change the fuel/air ratio; more oil=less gas=lean running=overheating. Oil has advanced further in the last 10 years than in the previous 150 years. Essentially ANY 2-stroke engine with a quality 50:1 oil will run excellent and be properly lubricated at a 50:1 fuel/oil mix. Running a 2-stroke at a 16/1 ratio will cause a very lean fuel/air mixture, ridiculous emissions, hard crusty carbon buildup in the engines combustion chamber and sludge in the crankcase and will very likely destroy the engine if run any length of time or under heavy loads at wide open throttle because of the lean fuel/air mixture.

An personal example is my 1970 Homelite Super XL saw, a strong machine made of all steel and has some real power...back when homelites where made in the usa and darn well made consumer products. The Super XL is one step below the commercial Homelite 360 model. The manual calls for a 32:1 mixture yet I run it at 50:1. It runs fantastic after adjusting the high and low speed jets to adjust for the richer fuel/air ratio (more fuel, less oil in the same space as well as more BTU's), it has more power, runs cooler, starts first pull, never fouls a plug and there is zero visible smoke.
