I picked up a slightly used Husqvarna 455 Rancher from a friend who needed cash 70$....and it uses a 50:1 mix. All my other equipment uses 40:1. Will using the 40:1 in the 455 cause any issues ?

Thanks

Nope. Many here would tell you to run 40:1 or even 32:1. I think your good to go at 40:1 across the board.

Check your tune of course. You might be running a little lean at 40:1 (cuz your using more oil and less gas than you were at 50:1) So might have to fatten up a little.


What oil are you running?
 
Just be sure to retune. More oil will slightly reduce fuel flow thru the carb jets, and make u'r tune a bit leaner. Some oils do this more than others, but retuning with a change in oil ratio or ethanol percentage is always a good idea
 
Pardon my ignorance, how do you cypher ratios? My machine uses 50/1 also. But I usually add a 2.6 oz bottle to 8/10th's of a gallon of 93 octane non ethanol, what does that come to?
 
What other stuff do you have that "needs" 40:1?

I run everything on 50:1 regardless of what it is "supposed" to have.
