They (Husky) sold it as a 372XPW. But, that can also apply to the west cost/full wrap version. So just because it's an XPW doesn't mean it will be 75cc. The 375K demo saw jug is the top end that is used.
Will be interesting to see how the 540 auto tune reacts to high heat over 30C. sbtree said a few posts back that he ran it from 23C to -8C and it ran the same. But when I ran my 550 and 562 auto tunes in 32 C with humidity they were crap for restarting after warmed up from hard cuts.
I assume you meant "fast idle". As long as this is not a reoccurring habit of the saw Husqvarna may have got the hot start problems ironed out, probably why it was held back from introduction for so long.Willard,
We had about 36 deg c today, in the shade. I only did about a tank and a half with the 540 but it seemed fine to restart when it was hot. At one stage i left it in the sun long enough that i had to put gloves on to hold it but it still restarted fine. Probably the only thing i noticed was when i put it down hot and didn't try to restart it for about 20 mins it needed half choke to restart and about 6 or 7 pulls.
When i get home ill try and remember to plug the diagnostic software into it and see what the max carb temp was
Where?
Please do let us know what you think!
