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

That means Week 18, correct?

Yes, 15Yes, 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"....
I know that Randy & Brad recommend 32:1 in all their ported buildsJust 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.
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 know that Randy & Brad recommend 32:1 in all their ported builds
Heres the IPL update bulletin for the new top cover.

Maybe so, but the evidence found inside these engines is quite clear. More oil than 50:1 is ideal, especially with strato engines.I believe so - but I have seen no evidence that they always are right, "blanket statements" seldom are...
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......

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!!
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.
