562xp Hesitation Question

[Locust Cutter]

First off, I'm not bashing the 562 as I love mine and as it's broken in, it's only become more mean. My question involves the off-idle throttle application: do any other 562 owners have issues with off-throttle acceleration? My saw always starts easily, runs out nicely (once warm) and cuts well beyond it's displacement. However, once properly warmed up and throughout each tank, if it idles for any period of time, when I hit the throttle, it initially bogs for a second or two and then catches and runs out fine, almost like it's either flooding or going extremely lean. No other issues and warm starts are just as easy as cold starts. I'm running fresh 87-91 octane gas and the Woodland Pro synthetic at a 40:1 blend. None of my other saws are exhibiting any problems off of the same mix. Any ideas sawyers?

Mweba just posted a video on YouTube that should help you out. It boils down to the pop off pressure on the carb is too high. Some have a stumble upon revving up and some have idle issues. If it's under warranty tell your dealer. You can start simple and reset it. If that doesn't work they'll usually replace the carb around here.

This is Mweba's video I'm not taking credit for the video or finding the fix. Just figured this may be helpful to the OP

My 560xpg has an exellent off idle throttle responce, the best one I ever have experienced - and it is an early one.

Well, I haven't been able to run it much, because of my health issues....

Mine just started exhibiting the same problem.

None of that with mine and it's two years old.

Looks like Mitch's fix (what Moody posted) will take care of the problem.

Not all of them have done or will do this. If your saw is under warranty tell your dealer what the issue is. If it's not then this video should help you find an alternative to replacing the carb.

Just curious why you are running 40:1? You state that it seems lean, since 40:1 is leaner (less gas per volume) that 50:1 and Husky recommends 50:1 and since it is an auto-tune carb I would think that viscosity would come into play with fuel metering. Your other saws are manually adjustable so the mix ratio can be taken into account. Maybe go to Lowe's and get a can of the premixed 50:1 gas and run a tank thru and see if that changes anything. I haven't had a better saw than the 562XP and thankfully I haven't had any issues yet other than the front of my bashed up because the stupid stock raker (aftermarket on back order from Baileys). Good luck, and hopefully something simple.

Ya I'm just stirring up the old ford/Chevy debate...like I've said before I enjoy reading most of your posts!

I've rum my 562 at 32:1 40:1 & 50:1. All run the same, auto tune doesn't care.

Same here, never an issue other than I didn't buy a 'g' model. Getting cold up here.

I only did 40:1 as the other saws seem to run a bit better that way (with equal tuning( and run cooler. I had also spoken with and PM'ed more than a few 562 owners on the topic before deciding to go that route. Occasionally I'll screw up and mix a batch of 50:1 and the result is the same, other than the other saws run a bit more richly...

MY 562 ran like crap when I first got it, a new carb fixed most of it but like you said it has a hitch off idle but that was/is minor compared to the way it ran at first. Now that I am mostly done cutting I will look into the repair. CJ

+1. Mine also seems to run equally fine anywhere between 50:1 & 32:1

This is exactly what my 562 is doing and the carb has already been replaced.

 

[skylogger]

Well i tried the spring trick that didn't work

 

[Locust Cutter]

Hmmm....

 

[skylogger]

My thoughts exactly.
