550XP Updates

My 550 doesn't care for a combination of 32:1 and cutting in short blasts. Otherwise it rips.

I am 1800799

That means Week 18, correct?

Yes, provided there is a year in front of that number....

It is made for short blasts - but not for 32:1.

Actually I suspect that the fuel people use some times is the reason they are having issues.

50:1 alkylate fuel with high grade synth oil is what they really want, at least "officially"....

Just found this video that shows the cutout on the new 562, he mentions it specifically at the end of the video.

First saw is my 550 followed by the 562 and 2186. Runs fairly clean at 40:1 but was a pig on 32:1

Just say no to 32:1/40:1! Lol I think you might be on to something with people running so much oil in the autotune/mtronic saws and having issues.

I know that Randy & Brad recommend 32:1 in all their ported builds

Was there a consensus at 32:1? I remember someone saying no less than 40:1 but I don't normally keep up on all of the oil threads.

I believe so - but I have seen no evidence that they always are right, "blanket statements" seldom are...

Maybe so, but the evidence found inside these engines is quite clear. More oil than 50:1 is ideal, especially with strato engines.

 

[blsnelling]

I recommend 32:1, no less than 40:1. I have heard of some member having issues with those ratios in Autotune or MTronic saw, but I've never witnessed it myself with the oils I use.

 

[SCHallenger]

Oh good lord.... don't say THAT..... his head is already swollen enough, ..... don't EVER tell the TROLL he is right, if his head explodes , he'll get messy grey stuff all over those pretty lil 346xp's of his......

LOL! That was a kind of tongue in cheek remark!

I'm a little confused by your earlier post that the info supplied was "old"(2012) & this post. What you have listed in this bulletin is the info I was referring to. Is this an old bulletin, or is it recent?

There is a new "kit" out for them consisting of a new carb, a new fuel line which is 26mm (slightly more than 1in) shorter than the original, & a new top cover with more room for air circulation to correct engine overheating which they have, apparently, determined to be the cause for some of P&C failures.
There were also some other changes which, I don't think, are part of the "kit". The changes, IIRC, involve a new crank, ball bearings, & needle bearing. I'm just guessing that these changes are part of an updated design.
The "kit" is on backorder & will not be available until June-----they say!!

There is no "kit" just ongoing product and individual component improvement. You don't want to know how many changes that POS 346 lived through!

I recommend 32:1, no less than 40:1. I have heard of some member having issues with those ratios in Autotune or MTronic saw, but I've never witnessed it myself with the oils I use.

The exact oil and fuel in the mix are likely to be factors then, and what Husky really want people to use is the Aspen alkylate premix. Stihl has a similar alkylate premix over here, that is called MotoMix.
