Dolmar 7900 modified for falling timber
Now lets start with the condition of this saw. It has approx 4 months of daily use on it. The only problems I've had with it was a leaky seam on the gas tank (Fixed but still leaks a little, not something to put in the trunk of a car). You can see the repair done to the tank in last picture. Also I have replaced the rear spring mounts and put the HD filter kit on as the stock air filter was plugging up every hour and a half. I have custom felling spikes on the saw made from T100 steel and 3/8" thick, they are guaranteed never to break.
This saw has a mild "Woods Port" on it and it really holds its own against must larger saws, like the 660 and 390. First I milled the cylinder down to 20 thou squish. Then I widened and raised the intake and exhaust to the maximum that the skirt width allowed and to return port timing back to stock. I have removed the baffling out of the muffler, port matched it to the exhaust port, and welded 2 more ports to it. Also I have advanced spark timing and removed the carb limiters caps and retuned the saw.
Also I am adding some more pics of the HD filter system that Dolmar has come out with. Worth every penny in my mind, adds power too! Also the compression on this saw is 172psi as you can see in the picture. Thanks,
