My first saw i bought at 16, P70 paid $380 back in1978, ran the shit out of it, making firewood and cedar posts, never had any issues with it. Sold it to a guy who was looking for a pro saw. $350 Todays current stable. P7000 plus P70, ive gone through P85 in great shape, its the large cube, saw. Way heavier than the small cube saws. 6-P55s and a couple S500s 2-Pioneer Partner 400s 1- Husqvarna 395, had 2 but, a local tree company had to have my other one ,with a 42" Cannon Superbar running .404 chain. Love Partner Saws.
I worked in the woods for a living one time. I bought a NEW R16 partner in the early 70's. After using old homelite's and mcculloch and pioneer saws I thought I died and went to heaven. I used to toss it in bruh piles and just stand there and watch it run upside down or any way it landed. They were so far ahead of ANYTHING else at the time it was stunning. At 30 below or 100 degrees....it just ran...no more down time.
Perfect power band!! The torq at peak hp not many of your Dyno pulls on any saws in the past line up the hat well at all! Great job. I garantee the if I hand file and tune your chain to that saw it will blow your mind.
I have a ton of saws from 42cc to 92 and believe it or not my favorite is my Partner 500. That little fucker is awesome. I found it covered in dust in a barn and it had barely been used. I ported it up and it is a badass little saw. Its not the fastest but it runs great. I like the design of the saw and they are built very well.
I have 2 of these old saws... they r factory untouched inside. My grandad logged with em, back in the day these were known as pretty hot little saws... stock they don't stand up to modern saws but I think they r awesome to mess around with... one of the few things I have from my granddad so they r priceless to me
Pretty impressive power gains. The basic partner designs were better than most other saws that I have worked on in their day, making for an easier build, with excellent results. The carbs on the S-55's have the built in governor, so a carb mod or replacement should improve the performance even more.
Great job! The first "Pro" saw i had! I wore out a couple of those cutting pulpwood in Maine. They were great little saws, only problems I had were electrical. I would like to find one to compare to modern-day saws!
Have a mint one I haven't done any mods to yet for some reason.. its just so nice like new couldn't bring myself to do it but its a fun little saw comparable to a husky 51 in power stock for stock..
Hi I build 1/5 scale rc car engines and some saws .I have a question why not take advantage of the bridge exhaust and go 70% of the bore diameter so you get more time area and turn that thing up .we run 50cc + and the clutch don’t kick in till 10500
Is there an industry standard that’s allowing you to interchange parts so easily? I understand from my industry (pwc) that most carbs should have the same bolt spacing, but I’ve seen you swap cylinders and pistons before too. Common manufacturers?
Most are close enough, and only being a single cylinder it is only 1 piece needs modified to fit. Same with most saws are roughly the same size per cc class, so cylinders are all close to the same dimensions etc. This one was all oem parts so far. Just some of the lesser parts (single ring piston) is more desirable for this "all out" type build. Lots of things are very different. But close enough it can work if motivated enough.
Yeah this saw didn’t really match my question but I’ve watched a bunch of your videos and wanted to ask. Thanks for replying!! More questions: do you follow a port “recipe” or is each cylinder taken individually? If so, how do you decide on the layout you want? The finished exhaust port on this saw looks much flatter and more aggressive than any other ports I’ve seen from you - was that because you have the bridge?

That thing is night and day different from what it was! Great job Joe!
That saw woke up! I would like to see how much the finger ports add one day when you are building one and have more time.
I find finger ports add more horsepower than almost anything else I do
Very nice!!

Thank you.. I sure hope so.

You woke it straight up! Well done!
Sure did!
Wow
I love the older saws!
You rock buddy!
Thank you
👍👍 dang nice improvement right there. Will be looking forward to the next episode of this build.
Ripper, definitely impressed!
Hey, I like the old partners. I found this vidoo pretty great!
Great work! Really came alive!
Next Up Porting and Dyno Tuning a Stihl TS-420 CutQuick😀😊😀
DAMN !
Looking great 👍🏻!!!!
Thank you!

Sweet gains Joe thats a mean lunch money taker now haha !!❤
Incredible man! Your not even done yet 😮
Save some trophy’s for the rest of us man🤷🏻♂️
Hey.... I still have to do my part operating....
Hahaha
Have a mint one I haven't done any mods to yet for some reason.. its just so nice like new couldn't bring myself to do it but its a fun little saw comparable to a husky 51 in power stock for stock..
👍🏻👏
Nice build
Imma be running my Poulan 475/505 conversion in the 85cc class. 👍🏻 Same as the 415/425, just single transfer and 54mm bore.
That should make a good runner. Sawfest is gonna be stacked this year!
@@dynojoemods2764 you dag on right. Everyone has got some mean runners, so it's gonna be very fun and exciting 👍🏻
Lol its like me, im a "PRE-fessional" haha
Jesus Joe nice build! I would really like to see a video on finger porting. How long would this build last with all day use?
Hi I build 1/5 scale rc car engines and some saws .I have a question why not take advantage of the bridge exhaust and go 70% of the bore diameter so you get more time area and turn that thing up .we run 50cc + and the clutch don’t kick in till 10500
I did go right to 70% much wider and the transfers will start to short circuit out the exhaust. Hoping a carb swap this will gain some rpm.
Great ok thank you for answering me .I love the channel and you do amazing work @@dynojoemods2764

Omg😊
Now i am curious, what about porting a P100?
Have never seen a p100 before
@red97.......Did you see my comment on the previous vid?
I did see it. Appears to be getting full throttle. I didn't do a tear down so not sure what the condition of the s55 was.
@@dynojoemods2764 cool
What sealant are you using?
Hylomar universal blue
@@dynojoemods2764 I am going to give it a try. Non hardening sounds pretty good compared to motoseal
Love old saws, don't have anything younger than 30 yo.
