Well thats no disrespect as I have one that has both ends ground down! :cheers:





The welch plugs just block of the channels in the carb that were there from the machining process. The small holes underneath can become pluged with junk and you need to remove the welch plugs so you can clean the passage ways underneath.

I think I said that so it make sense.....

dirty and just needs some diaphragms replaced.

If theres any doubt I pull the SOB's. Not hard at all and only takes a short while to do. Less time for sure then pulling the carb back off and removing them anyway.


Replaced carb from my 245A and Dayton runs and idlies great. GUess I need to relook at Dayton carb. Interesting situation with the replaced carb though. In tuning carb I noticed that the leaner I set the Lo screw the faster the saw ran. Unlike my previous experiences with tuning, my other saws will speed up and start to die as you richen and lean the lo speed needle(halfway between the two extremes is your setting). Kind of weird and I wonder if this is an issue to rectify.

Sounds like your making progress Bob. I sure hate to try and tell someone, that probably knows more about it than I do, LOL, But I ususlly start with the low side, get it to where it will accelerate good, without stumbling or blubbering, while getting up to speed. Then I try to set the high speed. Then go back an see if the the low end needs any changes. And of course set the idle with the idle screw. Sometimes it takes me several attempts.:dizzy: And I'm still never sure I got it right.
I have a hard time finding that midpoint you speak of on the low side.

:cheers:
Gregg,

Gregg,

That's exactly what I did Gregg. However the Lo side adjustment just keeps speeding up the saw as I lean the screw(clockwise). Never had this happen on any other saw. I just set the LO speed to where it accelerates smoothly and the HI speed by sound. Haven't cut with it yet as we've had 6 in. of rain in 18 hrs. Plug looks okay but I think I can lean out the HI speed more as the plug isn't light brown yet.

Right you are. Do you know the purpose for the welch plugs and the effect due to bad ones?

Here's why it's good to replace welch plugs, Bob. This is an HL-84A from a Poulan model K bowsaw I'm working on. You can see than blob of nasty looking stuff underneath where the welch plug was. (Large orifice near the top.) I didn't use to replace them but do more often than not now. Just have to be careful punching through the plug to as not to damage anything underneath. I personally like to use a drill press with a small bit. For me, it's easier to control pressure so as not to do damage.

BTW, don't know if this carb is going to make it. You can see the pitting in it from years sitting with old gas and moisture in it. Several other serious issues to deal with on this saw as well. No fire for one.

As long as the top end is good on your k bow saw you should have no problems getting it running. More than likely all you have to do is clean the points and it should have fire. When those saws sit that long it is best to go through the oilier as well. Those saws were a well built home owner saw.

Bob you might want to run that saw just a tad rich for the first couple of tanks.
Let it wear back in with a little extra lubrication.
I'm always afraid that I left a burr or rough spot when I clean a cylinder and piston.
I'm glad to hear it is up and running.

Bob, if you keep going leaner on the L screw it will finally die wont it? If the L screw is overly rich to begin with, then its normal for it to speed up some when leaning it out.

If all is right on those carbs, and your saw, your needle adjustments will be very, very close to the original 1 1/4 turns out that you need to set them at to begin with.



I had a 655 and in my opinion it is not as well built as a 5200.

We share the same opinion on that. There are some things on the 655 that look downright fragile for a 99cc saw.

Then I guess I won't offer you this 655 for $25 like I was going to. Guess I'll just have to keep it. :greenchainsaw::greenchainsaw:
 
The last one that I had I traded a bicycle frame for that I paid 20 bucks for at a garage sale!:greenchainsaw:



You sure have made some good trades over the years!!!
Pity that you can't find them now the way you used to!
Just Imagine what you would be worth if you had hung on to all of those saws 'til now!!!:cheers:

It's a pittythat I sold out on my poulan collection (Over 50 of them) not long before I found this site. I can't believe that none of you bought any of them on ebay. Although the 655 did'nt go to ebay the 5200's, 8500 and my 505 did. The 505 with 36'' bar brought just about what I paid for it from Bailey's (499.95 without a bar and chain) The 8500 brought around 400.00 on the bay. The 5400 went to a local buddy that is hyper as he11 and he straight gased it and sold it back to me for 40 bucks then I put the last good top end from a 5200 that I had left on it and ran it for a while and sold it on CL for 250.00. The other 505 went to the old man for X-MAS. The 655 got traded for a set of 35'' boggers for one of my mudd racers. All of the smaller ones left in the wifes garage sale and such except for the 7 poulans my brother left my house with for free. Here's the one that will blow your minds, the S6000 screwed up on me and I could'nt get it to run right so it went to the local scrap yard with it's 36'' windsor speedtip and .404 semi-chisle chain.

Told the wife I was selling them all and keeping old faithful (my 306) and buying "1" new saw. I had the 575 husky picked out on the web and went to the local dealer which is a Stihl, Husky and Echo dealer and it took him about an hr to talk me out of the 575 and into a MS460 which I'm glad he did because I really like my 460. My wife about sh## down her leg when I came out to the truck with a STIHL! I always said that I would never own a stihl.

Then I was searching about the 460 on the web and found AS and here I am!!!

AS starts a whole new frenzy. Next thing you know I'm out buying every new Stihl on the market that I could seem to afford even if I could'nt. 460, 170, 192, 310, 210, 260pro, 270, 361, 2-660's. Told myself I was getting out of hand again and started selling them off on ebay again and kept my 2 favorites the 260 and 460.

Well here I sit again with 19 chainsaw's. See Mike this CAD thing never leaves a guy no matter how hard you try!:cry: Either way it eats at me that I got rid of all them poulans every time that I get onto this POULAN thread!

What a DUMBAZZ I am huh. I think about rebuilding the poulan collection sometimes but I get PIZZED off when I think about what I already had!

Not to mention the recent interest in the old green the last couple of years for some unknown reason :dizzy: and how much MORE it would take to get you back to where you were.

Mark, I think I'm at 1 1/4 open but I'll check again tomorrow. Man, I kept going leaner and it kept speeding up. Sorta concerned me cause it was roaring and wouldn't die. Consequently I stopped for fear of doing damage.
