Chainsaw Repair

There were a few different part numbers for cylinders on that series. Two main things to look for on your saw and the cylinder donor:

1)Bore diameter (as there were 34cc and 38cc versions). You can swap a 34cc p/c set onto a 38cc crankcase (and vice/versa) so long as you don't run into trouble with #2 below.

2)Whether it has points or an electronic ignition. The two ignitions have different mounting provisions on the jugs. They're not compatible.

You can put an electronic ignition jug on a points saw if you also swap the ignition with it. Don't know if the flywheels have to be swapped too (they are different #'s, so I'd keep the matching FW with the ignition if possible). Can't remember offhand if the electronic ignition saws have the points cam omitted on them. Without the points cam, you of course couldn't put a points jug/ignition on an electronic ignition saw without also swapping in a points crank (that's IF the points cam is omitted on the E/E cranks). The electronic ignition saws do have a different crank part # than the points saws.

IIRC, all of the 2.1ci/34cc versions had points. There are two different electronic ignition 2.3ci/38cc cylinders. I have examples of both cylinders in my saw boneyard............just haven't gotten around to comparing to see what if anything is different between them. Interestingly, the piston and rings also have different #'s for the late electronic ignition saws. I need to look at those too. Also should look at the electronic ignition saw cranks to see if they still have a points cam. They probably don't....


Cylinder part #'s.

-530011236 replaced by 530011244 2.1ci/34cc saws. 1.438" bore. All had points.

-530011245 2.3ci/38cc saws with points. 1.5" bore.

-530012072 Earlier 2.3ci/38cc saws with electronic ignition. S25. S25DA. S25-CVA.

-530012664 Late 2.3ci/38cc saws with electronic ignition. Late S25DA and S25AV.

It sure had a lot of carbon.
