I use 40:1 mixed with high quality 2-stroke oil. I have used this mix in 1000s of chainsaws without any problem.

The carburetor on a 330 Homelite chainsaw can be adjusted with the 3 screws. Turning to the right increases the richness or gas flow. Turning to the left increases the air into the mixture.

32:1 or 40:1 will work just fine.
The 330 displaces 3.3 cubic inches, which is about 54 cc's.
The longer screw is for the idle speed. On the carburetor you will find little letters cast next to each needle adjusting screw. H is for High, and L is for low. http://store.chainsawr.com/
turn both hi and low fully clockwise till seated. then turn each 1 full turn counterclockwise then adjust your idle speed with idle set screw.

The location of the fuel filter on a Polaris 330 Trail Boss is in the fuel line that connects to the fuel pump. The fuel pump is located on the driver's side of the motor.
There could be a fouled out spark plug that would cause this. However the carburetor is the most common issue with these symptoms.
The fuel tank on a Cat 330 has a capacity of 164 gallons. This allows for extended use on the job site.
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.
