What a dream saw

What a dream saw

Thanks, a favorite cord wood saw .

 

[RCBS]

Gents, I have 'opportunity' to take possesion of a somewhat whooped on 543xp. It's rough and not making much air. Ex side of piston looks fine but I'm only seeing ~50lbs on the guage. It's got a broken flag, bent handle and the on off switch is wonky. Does make spark. No joy with some gas down the plug hole.

Is it worth any time/money to try to revive one? It's free to me.

I found a Husky 136 at the dump missing the clutch cover, recoil and has a scored piston and possibly some scoring on the cylinder, but found it worthy to bring home and revive. I figured if anything it could be the "loner" saw when someone comes and asks to borrow one!

Got a family picture of the all of the Husqvarna's I have:

Front to back:
* 136 (dump find)
* 440 (well used store loaner saw)
* 55 Rancher (dump find)
* 455 Rancher (customer returned to store - said "was a piece of junk")
* 272 XPG (dump find)
* 2100CD (dump find)

I probably have some parts for you if you get me a list or maybe you can have the whole box

I'm going to the wrong damn landfill...

That list didn't include the 046 or the plethora of Wildthings that were there too!!

Further teardown revealed a broken case at the flywheel side where flag attaches. No go. It was either dropped from a bucket, or run over.

Husqvarna thread is not too active here but I will ask anyway...customer brought in a 240 that he only uses occasionally, as in once or twice a year. I went through it last year with fuel lines, fuel filter, carburetor kit and it worked fine for me but he says it dies after making a cut. He is using canned fuel and it looks and smells good.

I ran it until it was good and warm and tried snapping the throttle off after running WOT and sure enough it would die. I tried adjusting both H and L a bit leaner assuming it was too much fuel but it did not cure it completely.

I went through everything on the saw, compression is 150 PSI hot, crankcase holds pressure and vacuum just fine, carburetor holds 12 PSI, I can't get much more out of my squeeze bulb tester so I don't know where exactly it might pop off.

He needs it this weekend so I am sending it out the door but expect it will come back again. What else should I be looking for? FWIW, it always restarts in a pull or two if I put it in the fast idle position, reluctant to restart after dying with the throttle at idle.









I did look through the carburetor again, everything is clean, diaphragms are pliable, inlet screen is clean.

Does it also die when you increase the idle speed just below the speed at which the clutch engages?

Tank venting issue, thought still weird because it restarts on fast idle. Maybe it thinks it’s a 562 mark 1.

In my experience, this is normal behavior. These and similar stratocharged Husqvarnas require a fast idle to restart. The information in the manual and on the chainsaw top cover instructs you to always use this throttle position.

Anyway, the procedure is the same in Stihl manuals, the difference is that Stihls tend to start in idle position, while Husqvarnas tend not to... At least in my experience.

Try ditching the canned fuel. Some of that stuff just doesn't have enough "pop" to it.

 

[fossil]

I'd check fuel and air filter and look for any kinks in the fuel line. I sounds like the carb isn't pumping enough fuel at idle. Some aftermarket fuel filters look OK but get restricted over time. Metering needle lever height?

I'm not sure if the fuel line on those is made from the tygon looking stuff with the liner inside that sometimes collapses.

 

[heimannm]

I replaced the fuel line last year with the good stuff from Echo. Fuel filter is clean, it behaves more like it it too rich after a cut. I did lower the metering lever just a bit when I had it apart.

We'll see.

If any of this were true, I would expect it to die when accelerating or in the cut, not when idling, where fuel demand is many times lower than when running at WOT.

Then check and tune the relationship between the Lo and idle speed settings. If they are off and one is compensating for the other in speed, can cause the issue you describe.

When I have encountered this very problem, a little more rich on the low side and a little more RPM on the idle screw fixes it 95% of the time. Some 2 strokes just don't like to idle down very low either. You may want to verify that the throttle is actually contacting the idle stop consistently. I've seen some of them that the throttle hangs open slightly most of the time, but then dies when it actually shuts all the way because the idle stop needs to be turned in more.
