I checked a number of different sites and most recommend 40:1. One user recommended 50:1 and the Mac I had a few years ago, as I recall, recommended that mix. The slightly richer mixture of 40:1 is always safe but it will smoke a little more.
Lossen the two bolts on the side of the chain bar, then use a straight screwdriver and straight under the chain turn the screw clockwise, don't tighten it to much, make sure it still turns, then tighten the bar bolts
I gather it is an MS310 and Stihl's oil mixes at 50:1
Mac 310 fuel/oil ratio is 40:1
That there is no fuel in it!
An oil tank for a Stihl MS310 can be bought directly from Stihl dealers. Alternatively, there are specialty shops online that sell chainsaw parts.
A barrel of jet fuel typically weighs around 290-310 pounds when full.
Which one? How many tens are there in 3,102?
310+205 of 310=310+ 20/100*310=310+62=372
310. If it was -310, it would still be 310.
