Poulan adjustable carb
We just received a Poulan pole saw from Northern Tool. I was very relieved to see that it has an adjustable carb, although the adjustment screws are not slotted. Instead they have very fine splines.
Searching ebay turned up a seller in Florida who has the splined screwdriver. We will wait until the screwdriver arrives before even starting the pole saw. That way it can be broken in on a nice slippery 32:1 oil mixture and a rich fuel setting for cool running and long engine life.
To get to this point on my 026 saw, bought 11 years ago, and Echo string trimmer, bought 8 years ago, I had to search out and install adjustable carbs to replace the fixed jet units.
Those 2 tools are thriving on the 32:1 oil premix and slightly rich running carbs. After a lot of very hard work the pistons still look perfect and the compression seems just like new.
