Title: Poulan pro 236
Post by: Cut4fun . on April 27, 2011, 05:51:00 pm
Just picked up the Poulan Pro 236 yellow version  :D. Mainly for my back up parts, but will see if I can make it a running trim saw first.

Looks just like my poulan 2100 in that thread. I bet it will be a runner when said and done.

Had to dump a little of what appeared to be WATER out of the tank and letting things dry up. Maybe it was ethanol gas that had separated?

Dragging up an ancient thread.  Was wondering if your PP236 had a chromed bore and bare piston.  Most Micro series saws have a plated piston and a 'naked' bore........................but some of the PP saws (such as the PP260) have chromed bores and bare pistons unlike their 'pedestrian' Poulan counterparts.  Was wondering if this was true with your saw.  I like the 2100/2400 rear handle Micro variants, and wish Poulan had done the same with their XXV series.

I'll check the PP236 sometime. I also have a good running 2100 I use.

Roger that is true for the most part.  A few yellow Poulan Pro versions of the WT family saws have chromed pistons and bare bores however.  PP220 and PP262 come to mind.

Post by: moparman texas on June 19, 2013, 06:58:49 pm
All gold Poulan Pro saws had chrome or nickel plated cylinders until sometime in the early 1990s. This was while they were sold at dealers; when Poulan started eliminating dealers and concentrated on direct retail customers, Poulan Pro just became another brand and many of their saws no longer had plated cylinders.

This PP236 hasnt had fuel in in since Apr 2011 going by my post in this thread.  I checked the PSI anyways and it pulled 120psi.

I also must have had the clutch off because it and the drum went flying across the floor while I was pulling it over for psi check   :-[ :D :D. I never did find the bearing or bushing for the clutch drum.

The plated cylinder looks good through the spark plug hole and with the muffler off. The piston showed a little light scoring on the exhaust side on top. Hope the pics can show it for you.

Opened up the 236 and found the air leak right away. 1 of the 2 cylinder bolts was loose and the base gasket was broken apart. 

I still think I can feel crank bearing movement though.

Cylinder and piston IMO could  easily cleaned up.

I've got one of these I've broken down and already had the cases powder coated. I have a NOS cylinder along with piston. My plan is to port it (add boost port also), carb from S25DA in the parts pile, advance timing, and then run it for my little limbing saw. I've already cut the ridge out of the cylinder and now need to assemble the bottom end to set squish and port map the cylinder.

Kevin, I really think with those mods that little saw could be a 200 eating machine. What does everyone else think about my plan?

I think it should be a really nice little saw when your done.   I am interested in the boost port and where you put it and how high you go with it.    Sounds interesting.
Title: Re: Poulan pro 236
Post by: Cut4fun . on June 29, 2013, 09:11:10 am
I ran a stock 2300av 38cc and I wasnt impressed. I ran a stock S25DA 38cc and I was impressed.   I dont know what the difference in porting numbers, carbs etc. But there is something there if I was building a gtg saw to look at the older.


You thinking a BP like on a 655 location. Otherwise I dont see where dual externals could be done like I used to see and had on one of my 5000's.

It would be interesting just with woods port to see.

It will be like the 655BP and the height will be the same as the other transfer points.....

530027482 for the ring.  The carb box gasket is 530019252 and is also supposedly NLA.

That's it.  Same gasket as what's used on the Micros.  That's why I'm surprised it's NLA.

That makes more sense.  I'll check it out.  Thanks Kevin!  The ring now shows available on ordertree.  Was NLA a few weeks ago....

Just checked.  That # is NLA on ordertree and ereplacementparts.  It's in stock and CHEAP on Jacks though.  Cool!

The 530019045 carb gasket used on most any older Poulan with a Tillotson HU or Walbro WA/WT also comes up as NLA, although some aftermarket replacements do come up on some sites....

He didnt say anything about the gasket in email back.

The 530027482 piston ring has long been discontinued.  We do have a large number of generic piston rings that may fit.  If you can get me the diameter of the piston (measured at the top), the thickness of the ring, and the width of the ring, I'll see if I have something that matches.  Also let me know the shape of the end of the ring (squared off, or beveled for pin).

Thanks,
Jeff

I think this 38.8mm  x 1.5mm Caber ring will work for you.    http://northwoodsaw.com/store/index.php?l=product_detail&p=1512



Now I remember searching info on a 2300cva once.  Trying to figure out your rings dimensions ?

Not for you just saving post here.

Do you know the bore in mm x thickness of ring in mm to see if can match something up. Unless it is one of those odd ball sizes like 36.33mm bore.

Is this the NLA part number 530037603 ?

Any of you other poulan guys know what the ring dimensions are?


Looking at rings on that saw they have 3 listed and all NLA.

530025467 Before Date Code/Serial #A1820001

530037603 Date Code/Serial #A1820001 and after

530027482 Piston Ring NLA

It's for a "Type II" 2300, I don't have a serial number on the chainsaw itself, it just says "type II".

Here is what I measured with my old HF digital caliper:

Bore: 38.83 mm
Piston ring width: 1.68mm
Piston ring height: 1.57mm
Piston ring open diameter: 40.87

Piston mid-height = 38.75mm

Your ring is 1.5mm thick I bet. Maybe get a 39mm x 1.5mm ring and file the end gap till it fits. $5 bucks for a Caber ring to try and see.

39mm ring to file ends and fit.  http://northwoodsaw.com/store/index.php?l=product_detail&p=1513

Wow that's very interesting.  I've never seen a Micro series saw with two thin piston rings.  Seen many different Micro variants with a chromed piston (and bare bore) and two thick rings.  Also seen a few Micro variants (such as my PP236 which has the same piston as a PP235 or 2350) with a chromed bore, bare piston, and one thick ring. 

This saw here is a new one on me.  Haven't seen that piston illustrated in the IPL's either (although the # for it may be there........as there are multiple part #'s in the 200/205/225/235 IPL).  Have you measured the bore diameter?

I still need to dig for clutches etc.  I know there was a older and newer but know of no cross overs.

I know I have 2 complete sets on 2 runners I dont use. Would sell the runners for the cost of the sets.

I looked yesterday. Extras not much. 1 spur drum with half wear but usable IMO. I wouldnt waste time on it shipping. Also 1 bearing. 1 old style clutch with weird wear on 1 shoe, again wouldnt bother with it.
 
The 2 runners have the nicer complete set ups I have.  Both run but 1 needs carb rebuilt. I just switch the good carb between them when tested.   Trade both saws for?  or sell the 2 complete set ups or trade for?

I'm curious about all the ring mixing and matching you guys do, and the plated/unplated cylinders.  Working on bikes, rings for plated cylinders are very different from rings for bikes with plated cylinders, and mixing them up ruins the bore.  With all the Poulan/Craftsman variants that may share bore sizes but not bore type, are you ever concerned about the wrong rings?  Or have you found it to be a non-issue?

I'm curious about all the ring mixing and matching you guys do, and the plated/unplated cylinders.  Working on bikes, rings for plated cylinders are very different from rings for bikes with plated cylinders, and mixing them up ruins the bore.  With all the Poulan/Craftsman variants that may share bore sizes but not bore type, are you ever concerned about the wrong rings?  Or have you found it to be a non-issue?

We dont mix unplated and plated they are only done in sets when swapped.

Wow that's very interesting.  I've never seen a Micro series saw with two thin piston rings.  Seen many different Micro variants with a chromed piston (and bare bore) and two thick rings.  Also seen a few Micro variants (such as my PP236 which has the same piston as a PP235 or 2350) with a chromed bore, bare piston, and one thick ring. 

This saw here is a new one on me.  Haven't seen that piston illustrated in the IPL's either (although the # for it may be there........as there are multiple part #'s in the 200/205/225/235 IPL).  Have you measured the bore diameter?

Guy posted a thread yesterday in CRG and here last night of his poulan pro 225 and it had thin rings.

Interesting.  I have never seen a PP225 'in the flesh'.
