Nik's Poulan Thread

[8433jeff]

Umm... did I mention the Poulan with that scored cylinder died because of the boot tearing off at the cylinder clamp? How common is it for it to randomly fail in such a way on this saw?

So if I worked on the piston and cylinder, made the measurements, and the piston to cylinder clearance is more than say, .004" or so, it's time to look for a new piston?

Real common if the AV mounts are tore up, and its common for all saws in that style if the AV mounts are bad. Age, oil, etc. all wear on such things made from "rubber".

So the boot tore there. Explain how your over thinking it solution makes it better? The clamp held, the boot ring is still there, the boot tore. Happens every day, many brands, blah blah.

Clamps failing, boots not stretching enough to compensate for AV travel, them are engineering problems, and there have been saws made that way. Without seeing pictures, from your description, this one isn't one of those. Just saying.

Got the 71A today!

I walked into the office and the department chair pointed to a box and said "your chainsaw is here!"

I guess they are on to me...

Seems to have great compression, and she's all there. The first thing that struck me about that saw is how light it is (relative to the other, older 5+ cube saws I've been stockpiling).

I was expecting a little more weight with aluminum construction.

No pictures? You know the routine!

I will say the 71-A is no lightweight but there not a heavy as they look, thats for sure. Not really bad at all for a saw of there displacement and vintage.

Funny about pistons...I had a Craftsman 2.1 with a bad piston, I just took some sandpaper and went around the piston several times until it was fairly smooth, did the same to the cylinder, put rings in it and away it went! That was around 20 years ago and the saw still has compression and runs to this day!

Never go all the way around the piston with sand paper. If your trying to clean up a score only buff the edges of the scores.

Never "sand" the tolerances out of the piston.

Ok, diaphrams gave out a little while back, made some that worked ok but saw would periodically overload on fuel and didn't like running below half a tank. Figured it was the homemade diaphrams. Got new carb kit and rebuilt carb yesterday, still doing same thing. Full tank, will run great but looks like carb is allowing fuel to drain through, pulled air cleaner and had fuel in housing.. Half tank, bogs down and shuts off. Refill and let set for a few, restarts and runs great till hitting half a tank again. Fuel lines are good, all gaskets in correct places, fuel drips out of carb intake. did same thing with "homemade" kit.

Any ideas what i missed?

Thanks,
Ed

By what i could find, inlet needle is set correctly. (Admittedly not an expert by any means) Fuel tank vent is good, no vacuum build up at all in tank. Wondering if possibly a compression issue, other than carb kit, saw is all original.

Is your carb a HS 59A or B, just making sure its original. What kit # did you use? A D&G kit or a full rebuild kit?

Leaking gas through the carb screams a inlet needle problem. Either a bad needle, improper adjustment of the lever or the wrong type diaphragm or wrong gasket/diaphragm order on install.

Stalling at half tank points to a cap vent problem, are you sure the hole in the top of the cap is clear? Is the duckbill stuck shut?

A plugged fuel fliter or bad fuel line can also cause troubles as well.

Are you sure the carb to reed adaper gasket is sealing well?

Hey guys,
Figured if any O e knows it's you guys!

Are all Poulan Pro 655's boost ported?

I read back awhile ago were there were black covered ones and gray ones.
Would that be a good indication. Thanks guys!

Matt,as far as I know the boost port 655's all read BP655 on the handle. The regular non BP saws just say Pro 655 on them.

I forgot, here is Chris B's 655BP so you can see the decals on it.

I had it sent to where I work to avoid unnecessary spousal scrutiny...I'll put some up when I sneak it home and into the basement.

Turns out blaze orange goes well with lime green!

Ah, the spousal scrutiny thing. Never had that here so I keep forgetting about it. :hmm3grin2orange:

Word of advice then, DO NOT start that thing anywhere near your place. She will definatly at that point know you got another saw as none of yours will sound like this one. Probably scare the hell out of any small children, wifes and neighbors as well.

I will try to remember to put up a couple of pics tomorrow.

I didn't think of AV mounts causing the boot to tear.

I will also try to remember to post pics of the AV mounts so we all can debate whether they're shot or not.

We'll see how tired I am after pulling a 7-5, possibly to 6:00 shift in the factory tomorrow. I just might forget, lol. Pops said it's busier than hell down there, and they could use the help. I could use the money...

Gotta get up at 6, drive for about an hour, work, work, work, eat lunch, work, work, work. That's a pretty busy day if you ask me...

G'night folks! :msp_sleep:

Thats why you is still the monkey. Could be wrong, but I wouldn't bet on it.

306 muffler on 245 bowsaw

I have a 245 bowsaw that the muffler had come-apart on, so I put one on it from a 306. Just wondering if the 306 muffler may be too restrictive? Runs good, but I have yet to cut with it.

Which 306 muffler did you use? FYI they had the same tin mufflers as the 245's.

If your talking about replacing the 245 muffler with the cast aluminum muffler from a early 306, then you will be fine as well, even though the 245 never came with that one as far as I know.

 

[tilenick]

I got a 306A from Ebay last week and noticed that the tin muffler is so close to the sprocket cover that it makes it hard to pull either one off. The other one I have came with the cast muffler and it is not a problem. Is there something I am overlooking? It runs great and idles great and cuts like a dream.
Nick.

Got her going. Thanks for your help everyone.

Must have missed something in the previous cleanings, tore carb down again, cleaned and reassembled. Everything else checked out good. Running great now all the way through a tank, no fuel loss either. :biggrin:

Ah, the spousal scrutiny thing. Never had that here so I keep forgetting about it.

I wouldn't be getting it if I didn't keep telling her to cut back on groceries, diapers, and medicine.

Word of advice then, DO NOT start that thing anywhere near your place. She will definatly at that point know you got another saw as none of yours will sound like this one. Probably scare the hell out of any small children, wifes and neighbors as well.

I remember firing up my 076 when my boy was closer to 3. He was so excited, and scared at the same time, he just stood there smiling and shaking. His fascination was exactly balanced by his fear, and he stayed glued to the spot.

I'll have to report back when he hears this one...I'm guessing he'll be headed in the opposite direction, even with ear plugs in!

$30 Craigslist purchase.

Doesn't wanna fire but the seller claims he got it to idle for about 15 seconds last week.

The bottom is in actually really good shape, only thing missing is some paint.

I'm somewhat familiar with these countervibe models but I've never seen nor heard of "Power Sharp" before.

Should prolly throw in a new plug and clean the carb out. Should maybe even buy a carb kit for it.

Needs a bit of work. Even so it was a great deal! Woot Woot!! :greenchainsaw:

Nice find WoodChuck'r, i'd have jumped on that too.

I think that Power Sharp system is only for power sharp chains. If it has anything else on it I wouldn't try to use it. Many, if not most, people changed them over to conventional chains.
