I run super vp premixed fuel

I mostly cut oak and I have a sharp chain idk if it's just the autotune or it just revs so high maybe that's why it eats so much gas

I have a 455 rancher with auto tune! after just 37 hours on it it was getting hard to start and when it did the fumes were very strong of fuel! it had to be re calibrated in the carb from winter when I bought it and broke it in, to summer use and dryer warmer temps!! after that I have not had any issues with the auto tune with a second winter gone an using it to do part of a 12 cord cut..... auto tune is a fussy little britch with a dirty air filter, be warned!!

Should I take it to my dealer

Chucker, curious as to how the re-cal was performed/accomplished?

Why, do you have a problem?

my local ace hardware sells the saws and their tech uses a computer to recal... took about 20 minutes as I didn't make it home and had tp go back to get the saw.... lol

 

[Jaret Dominicus]

I think I might bring mine to my dealer and see what's going on because I don't think it's normal to refuel every 20 25min

!! YES THERE COMPUTERIZED.. LOL like everything else these days?

I like old fashioned better but I figured why not try the autotune I thought that all the bugs and glitches were fixed on them

Pre-mix is pricey around here (appx. CDN $10 per litre), so if I was running that exclusively, I'd be unhappy with any saw. I run pump gas 91 octane with no ethanol (about CDN $1.15 per litre) at 40 to 1 mix and I'm guessing I can buck up a couple of 35'x20" logs on one tank pretty easily with my 60cc 562xp.

Not sure if you have an issue with your saw but you might get it checked out just to put your mind at ease.

It's a hot rod. They burn lots of mix. No way I could afford to run pre-mix, all mine (except the 562xp) are ported gas hogs! I run 91 E-Free with Lucas oil.

I'm gonna have to start mixing my own fuel lol

And I use the Lucas air cooled as well for mix oil, good stuff, less than 10 bucks a quart. I run 32:1, 4 oz per gallon of gas, easy to remember, makes good power and keeps everything good and lubed, top end and bottom end.
