Let me start out by saying I am not a fan of the Farmertec homeowner or rather clamshell engine parts. With that said I have ended up with a handful of MS 210 through MS 250 chainsaws that the engines are junk in. I only give about $25 for the complete saws. I then put a $30 Farmertec engine in them and that put them on a local auction sale. Recently the last two engines have been very doggy. I run all of them for a couple tanks of fuel to make sure they are semi-broken in and tuned properly. Both started out with around 120 pounds of compression cold before break in and have ended at about 135 cold two tanks later. For a Farmertec clamshell engine that’s good compression as far as I’m concerned. The problem I’m having is they are slow to accelerate and under powered in the cut. They pressure and VAC test perfectly. Cylinders look great after break in with no signs of streaking at all. In both cases they are OEM carburetors, intakes, fuel lines, and mufflers. Spark arrestor screens are clean as a whistle. I’m guessing it is a port timing issue just wondering if anybody else has sen this?
