Thanks on the saw.    I had to actually do a lot of work on that saw.  New piston and ring, two of the engine mounting bolts were broken off and needed drilled out.  One of the metal bushings for the engine mount in the plastic was missing and made another on my lathe.   I probably have more into it than it is worth.   

    I did take it up to Wyoming last year and helped the BIL cut firewood at 8000 ft.  The BIL looked at me funny when I got it out but it kept up just fine since all we were cutting was beetle kill pine.

Did you have to touch up the needles a little in Wyoming at 8000 ft.

My son took a plastic Mac with him to Wyoming and it was only 7000 in Big Piney. I forgot to show him anything about adjusting needles. He sawed some on a cottonwod or two and never said anything about the saw not running right. I had set the needles here where it is 1000.

Oh yea the first thing I did was to get my little splined Poulan carb adjuster out.   It would barely idle.

Well I have a 2750 running full comp 3/8ths on a 12 inch bar that is a BEAST!!!
Also a PP295 running .325 on a 16" narrow kerf Husky bar that is a SUPER little limbing saw!



Mike
Mine is a 20" with .325 chain.  Throws chips like a "B" it is my bucking saw, I LOVE the way it runs!  I liked it so much that I bought a 4620 avl, put the bar/chain/sprocket off of my 2150 on it (16" 3/8 lp (had several bars, and a mile of chain to use up!)). Anyway, the 4620 cuts just as good, just doesn't oil too well, working on that right now, I'm sure that I'll get it figured out.

I have this PP 295 that I modded about a year ago.    I did some porting nothing serious just widened the exhaust and intake some and then of course muffler modded it.   I have another that I am going to get more serious on and see how that does.   Just thought I would add a couple of pics.

I like the mods...someday I'd like to learn how to get just a little bit more out of an already great saw!

Well I have been working on another Poulan 295.  I like these saws they are easy to work on and modify and respond very well.   I put a .325 18" bar on this one with a 7 pin rim, and yes I did find a rim sprocket for it.   I did a compression test before starting and it was 150 psi and really not bad.   The squish was at .040".   

  So the mods I did I took the lazy way out and did not mount a degree wheel to check any of the numbers I just modded it.    I raised the exhaust port just alittle and widened it.   I took the muffler apart and cut the deflector open and put a spark arrestor around it.   I then double ported the outside of the muffler and matched it to the the exhaust port on the engine.   Then I welded it all back up.

   The intake port I widened and lowered it alittle.   The transfers I pointed toward the intake port but did not raise them.

    The squish which was .040 I took it to .020" and ended up with 160 psi.    So I am happy with that because I raised the exhaust port.    Next I checked it for free porting because the cylinder did drop by .020" and no free porting.   

   I did put new main bearings and seals but I kept the same piston and rings in it.    I then advanced the timing I would say around 4 degrees.

    The saw started real easy and idles real good.   I tuned it in some wood and with good 4 stroking was able to get 14,000 rpm out of it so far.   

  All in all I am happy with the out come and with the cost of the power head at 50.00 and the bearing and seals around 20.00 and have a but kicking little 46cc saw for 70.00 bucks.   Here are a few pics.

This is the redneck chainsaw repair forum right.

I made this to the exact width and the exact diameter of the 295 crankcase and where the bearings seat.   Then I mounted the cylinder upside down in my vise and set it in there and applied pressure equally to both sides.   Rotating the cylinder from side to side and taking lots of measurements.   I pressure checked it when I was done and it was nice and tight with no leaks.
