Chainsaw Repair

So this is my latest Dolmar that I have aquired.   I did not have any spark when I got it and finally found a donor saw with a good ignition for a resonable price.  The muffler was beat pretty bad so once again I used the one off the donor saw as with some of the antivibration buffers.  The muffler was dented pretty good with weld on the outside all around the mounting screws where it had started to crack.  So I ground all the old weld off knocked the dents out and welded it from the inside so it would not show.   I also removed the old stock outlet and put in a double pipe.   The baffle on the inside I cut away about half of it and put a spark screen around the baffle because I will use this in National Forest land and it is required.  Saw runs excellant and just thought I would show the MM.

 Once again not a high revving engine but lots of torque with good compression in these saws.

I owned a 119. It was one of the strongest 60cc saw i ever owned. But it was on the heavy side.

Well the 119 is all magnesium including the filter cover.   So you are right it is on the heavey side, but when I get to the point I cannot lift one of them, maybe it would be time to give it up anyways. 

I have never ran a Poulan 4000 but I have my 3700 and 395 and I believe it would outcut the 3700 and close to the 395.  It was common to find the Dolmar 119 with 170 to 190 PSI from the factory.  The Poulan saws do not run that kind of compression unless you drop the cylinders in them.  Another thing is the Dolmar is a closed port cylinder and the Poulans are open port.  A side by side test would be interesting.

    Very nice 660Magnum.  Here is a pic of my 119 for comparison.
