Hey you're back! Or maybe I just hadnt noticed you posting. Never heard how that saw turned out that I had machine done for you. Now a days I have my own lathe so if you need something done let me know. I hardly charge for the work. Just want to help guys out.
Thanks for the offer of lathe work! I built two 2100s recently and machining would have helped a lot on the squish bands of the sleazy jugs I had to use.

My P45 ended up pretty strong, turns very high RPM, and still has Pioneer torque. I've cut a lot of wood with it. I was doing some cutting with some friends not long ago, and one of them signaled he wanted to race. His 066 wasn't even close. I always tell guys, though, that I cheat: My chains are fast.

I think I told you that i eventually figured out the machinist had done things bass-ackwards and took .041" out of the squish band and .020" off the base instead of the other way around. I was confused for a week about having a headbanger and a huge squish at the same time! Once I found it, I ground off the thin .041" ridge that was left in the top of the jug and ended up w/ a squish of about .024" with no gasket.

A friend was here last summer with his PP455 (same saw) that had been rebuilt and built by a known saw builder. It needed new main bearings, and we got that done. We ended up putting the jug on w/ a paper bag gasket for a squish of .017" Close! Serious compression in that little saw. We did some timed cuts, and his may have been a tad faster than mine.

The porting of the two saws is essentially the same. I know this won't sound right to you, but the exhaust ports are up around 96 degrees.

Are you saying a ported 72cc saw can clean up on a 92cc Stihl? I would love to see that
 
You know sitting here thinking that I haven't read a book in probably 20 years but I have read about 250 pages of this forum lol. It's great information and people. Ty I've been working a p41 to 42hp upgrade. First pioneer or chainsaw for that matter I've ever really worked on. I'm enjoying it. So much info if a person is willing to look. Thanks again

Hey Fellas
I am just starting to get into collecting and restoring old Pioneer chainsaws.It would be great if some of you guys that are into Pioneer saws could show some pictures of your Pioneers.I currently am starting with a P25and1073.It seems to me that there are a few saws in the pioneer line up that have the same specs but just a different model number. Does anyone know why? For example the P25 and the 1073 .I think they are identical except for the starter .I have briefley looked thru printed manuals I have and sort of came to this conclusion.May be I should be a little more thorough before starting this up.But would like to see some pics from Pioneer lovers.
Many thanks

I was so impressed with the power of the p 40,s and p50,s that I had to buy every one I saw. Here is my first P 50 , recently restored. 15837622970583778573717207011309.jpg15837624978846620150787030929400.jpg
 
I bought this bar off ebay. I purchased a 18 inch Oregon chain which doesn't fit. Seems a link or 2 short. Can anyone tell me what this bar will fit??

Did you get a oregon 68 DL chain in 3/8 or .325? There is a difference! A 68 DL chain of 3/8 should fit it, that is what the bar specifies in the stamping.

Your question states you got an Oregon chain for an 18" bar, Did you get a 3/8 or .325 chain.

If you did get a 3/8 68 DL chain and your saw is equipped with a rim sprocket it is entirely possible that you are not lining the chain up with the cutouts in the rim. The chain could be riding outside of the rim sprocket instead of engaging the rim. By not engageing the rim it is going around a much larger radius ,thus taking more of the chain there and it obviously then wont be long enough to fit over the end of the bar.
