The 572XP Update Thread

I’ve done the vent mod on the ported one but the three other stock ones we run I left it alone cause it seems to work fine. Guess it’s only once the saw is ported and the need for fuel increases? Pretty typical mod to do on other ported saws as well.

I've been using the Echo tank vents in anything that I can. They seem to work very well and don't require modifications, or at least thus far.

Seeing a number of brake levers broken on this model. All right above the middle cross bar. This being saws in use as well as a brand new one. Was curious if other folks were having this issue or was it just a localized quirk?

It is a somewhat known issue, several came into my local dealership with their brake flags broken. Seen it elsewhere too. Id chalk it up to brittle plastic AND crappy packaging for new saws.

The plastic on brake handle doesn’t seem quite as strong as a 372. Especially in the cold. I replaced 2 so far. It wouldn’t be that hard for them to incorporate a running change to a stronger material I would think?

I've been doing the same for years. They also release excess presure too.

Adding an Echo tank vent at the end of the hose won't really help the 572 vent issue. The problem is at the opposite end of the hose, where it attaches to the tank.

It will if you open up/ gut the tank end and just run echo on the end of the hose

That was the point I was making.

Understood my friend, I was unaware the venting issue was on the tank side!

I have recognized yesterday, that my 572 starts cold without the choke. It only needs 2-3 pulls and it runs. Anyone else saw also starts like this?

I haven't tried starting mine cold without the choke, but I would guess mine would not start like that. 2 pulls on choke, and one with it off usually gets it done.

 

[Woodwater]

I normal also 2 pulls with choke and then one off and runs. but yesterday morning i have tried it, and it starts. today the same cold.

Just for grins I will have to try it today.

I’ve got a couple 7910’s that regularly cold start on 2 pulls without the choke. One pull with choke if I’m quick enough pushing the choke lever in.

So, I quit after 15 pulls with no start. The saw started to pop at pull #11, but she wouldn’t start. Needless to say, not gonna try starting without choke.

I'd bet on @Karavankasbear saw the low side mixture in overly rich right now for some reason.

Throttle plate setting open a hair too wide?

 

[huskyboy]

Popoff is probably a bit low. Just like a lot of 7900/7910 zama are.
