325

I noticed your poulan pro and wanted to ask a question about somthing I am doing. I have a nice looking 325 case w/flywheel and clutch but no p/c . If I put a 5000 p/c on that case will it work? Thanks I have this also in the main chainsaw forum but you guys may know best here thanks, Jeff

It will work fine, the 325 just had a spacer under the cylinder for a taller piston. The 325/590 cases are improved 5000 design with larger SKIRT hole in case to take ALL cylinders. 325/590 cylinders won't fit 5000/490/500 cases without mods.
Use it there GREAT, or even better!!!! Pay lots of $$$ for a 55mm 325 top end and Spacer and have the BEST!!!

Hey Duane
I have a question about 2 - 3 weeks ago I posted a few pictures of 3 saws and 1 parts power head. I did that so that some body could tell me what they were,- one was a r517 one was a f-55-a, and one was somthing else? cant remember now one was a/v and one was not .Where can i look to find that post? I did a search under my name and it is not there.The question I had was I thought someone told me that the r517 was a 70 cc saw ? but I cannot remember thats why I was looking for the post. I have them all 3 running great and I wanted to keep the largest one maybe. But from what I can see although they are diffrent looking and diffrent numbers are they all 55 cc? While I await some help for my feeble mind I will google the f55a.Thanks JEFF

Pretty sure you have all 55cc, 65cc cylinders will extend slightly toward the muffler on the top, 55cc are pretty squar'ish, If it were me I'd keep the 517 as there not as common. The farmer could be a 55 or 65, clean real good behind the coil bracket and find the numbers. Some are on the other side.

The non AV thin, small cooling fin saws have a little more power!!!!! larger bridged ports.

I'm at a point where my brake band on the P500 is in need of replacement. Getting the spring compressed so far has been a bear. If I can get that end freed up the other is just held with a short roll pin...that I can handle. Just wondering if there a tool above that we need or trick that someone knows? Right now I could sure use some help.

Ok Duane i will keep the 517 as for the other two ,If the cylinder fins are stacked pretty straight up it is a 55cc if the fins stack up and slightly foward it is a 65cc? If that is how i can tell thats easy enough to do.
On another note when I have the recoil off the 517 at the coils there is a 2 peice coil arrangement one larger one smaller what the hell is that all about? on my 5000's 500 and such they have just the 1 coil. Is this an early attempt at getting away from points? In the pictures there are 3 saws with bars and one just partial powerhead, I have robbed the handel for the 517 what do you suppose that one was i think you said that may have been the most powerfull of the bunch. I guess I can keep that one for parts for the 517? How the hell did you know about these old saws anyway.

The R517 is 55cc.

Well I'll start with, I learned about these by Buying everyone I could find last year, then taking them apart, I am still finding out interesting things on every one. I buy them if they look weird or different in any way. (there all different)
There were (3) electronic ignition systems used, first is your 2 peice Tyrister, second was the Ignitron using a special coil but had a solid state module mounted in handle under start stop switch, (also early 500/5000 mounted under carb) third was regular EM Elux coil common to all Husky Jonsered saws now.
These saws can all be converted to new Elux coils easy but timing is (sometimes) a little advance making starting a little tricky . And depending on year the start stop switch will work opposite. Early saws grounded to run newer ground to stop.
Coils can be Id'ed by either them saying Partner (solid state module only) or newer coils stating Em Elux, or Ducati.
As for Power the closely stacking cooling fin saws had more aggressive port timing with bigger ports, most were closed port. Check your 517 to see if it is closed port by looking through Spark plug hole. My findings have been Bridged ports (intake/Exguast) Partners scream.

Been working on the Poulan 325 / Partner 500 jug and Piston project today

I will get back to looking at the older ones soon .It is really cool that you know so much about these older saws
It's kinda too bad you dont know about newer partners ,......CAUSE boy do I have a question or 20 for you. ha ha ha
Alright here we go I put the 5000 jug and modified a 246 husky piston( opened up the boss's) onto the 325 poulan pro case today. I have no knowledge about the 325 bought it as a case only, thought it was a 500 or 5000. Price was good so i didnt look a gift horse in the mouth. Discovered it was a 325 yesterday while cleaning it for a new piston. And then i asked you about it so..

With no base gasket in place the piston hit the jug top (combustion chamber ),,,added a 0.45 gasket to the base still hit, added a 0.20 gasket on to that still hit, so put 2 of the 45's on and ended up with about 0.21 squish. checked it about 20 times cause the p seemed to still tap the top on occaision? Anyway I was satisifed it was not hitting after checking squish again so put on the flywheel. Suprise it has 2 keyways and I did not notice which k/w it was on when i took it apart. So I lined up the coil field points and the with wheel and piston at tdc and put her together. Got good fire.Then clutch. Recoil,and a little prime and it ran till gas was gone,,, prime run till gas was gone,,, ect about 5 times. Gas all over the carb area like it is leaking? Said well i will pull the jug and see if the piston was hitting someplace all looks great no marks at top of cylinder or on the piston. Got to looking at the carb i put on well guess what i had robbed the diaphram awhile back hence the leak and not running ( holy shi$ HOW DUMB CAN YOU GET) so I robbed a diaphram from another carb and went at it again.
This time it runs but after you rev it ,it takes awhile for the rpms to come down? So i adj 1 1/4 on both (h) and (L) Idel screw at 1turn after contact with throttle lobe. After a bunch of adj's it still comes back from a rev of lets say 5000 rpm VERY slowly.I am in hopes it is a caburator issue.Or is it a Flywheel issue? Or is it a case because it had leaking seals ? So to sum it up it runs but somtimes will idle and sometimes not, when you rev it ,it takes 3-7 sec to return to idle, and it is possible i have the flywheel on the wrong keyway.What -O- Partner Swami is my issue. Hope you hear from ya soon Jeff

My bet is on the air leak by a nose!!!

Yeeeeeup, I'd put money on it.

 

[Jeff Lary]

You mean seals? If so can i change them w/out opening the case? Make a pick thingy and dig em out then replace em?

Yes ,you can replace the seals without splitting the case. It could be the carb boot too.

 

[Modifiedmark]

Check the throttle linkage to make sure its not bent and binding.

Been there, done that.

 

[Arrowhead]

Jeff, I have some NOS 325 spacers you need for the proper clearance.

On your air leak... Is the rubber sleeve that goes into the jug, that seals the intake impulse port in good shape? I'm not talking about the the one that goes to the intake port on the jug, but the pencil size diameter one below it.

You can replace the seals without splitting the case, but you need to remove the oil pump worm gear. You need a special puller.

Partner 5000 on 325

The question is WHY do you need the spacer with a 5000 cylinder? All cranks are the same 500/5000/490/590/325, the 325 has a taller piston needing the spacer, the others all do not.
I put a 490 and 590 P/C on new NOS 325 cases with NO issues.

Guess I'm confused on your combo, sure you have the right piston?

OR!! are my cases not 325? Did they mill the tops of 590 cases down for 325's, thought I checked and the part#'s were the same.

I have a parts saw 325 with a 5K+ CP cylinder. It doesn't have any clearance issues.

What is under the cylinder for gasket?

 

[nmurph]

I will measure the gasket, but it wasn't anything thick.

No gaskets on any of my saws, except my REAL 325 saw. 490/590/500/5000+/325 hybrid 490/325 hybrid 590/ Husky 55 hybrid 5000+
