jonsered air filters

[kdhotsaw]

Hello Huskyman
sorry about the delay on the question about 670 jonsered air filters. Trying to remember if that particular saws air filter assembly is similar to husky's 268. K @N filters seem to plug up very fast in dusty conditions. the newer 372, 385, 394 and 395 filters are high quality filters. but you would have to cut the rear portion off of your top cover to use them. also all of the older 90 degree turn elbows between the carb and the air filter require a lot of work to remove the restrictions, Grind out all the sharp edges, enlarge the passageway etc. what we do now is use the late model 372 elbow on the earlier saws the elbow is much larger and much more free flowing. it also is about 1/4 inch farther back from the choke plate . this helps straighten out the air flow before it reaches the choke plate. 0n a 288 we were testing we could go from a 13.6 second cut to a 11.1 second cut by removing the choke plate, choke shaft, and the elbow and filter. so it makes a real difference to straighten out the airflow and remove obstructions

Isnt the saw difficult to start w/o a choke?

Hello Huskyman,
Yes they are a little harder to start. The fallers like the green weenie type filter, the soft foam type filter. they just push them downto seal off the inlet , crank them a couple of times to pull fuel in and they start. I like the late husky filters much better. If you cut the rear of your top cover off to fit these type filters the biggest problem we encounter is when it rains. We've converted some of the carbs over to a priming bulb type choke system, the early 3120 husky had this system . it works well and allows you to remove the choke plate and shaft. If you can gain 1/3 horsepower it worth the effort.
