Need to know what brand it is, probably will be 50:1 or 40:1
The gas to oil ratio for this type of trimmer should be 40:1. Sears sells the premixed fuel for $4.99 http://www.sears.com/shc/s/p_10153_12605_07136521000P?keyword=fuel+mix
It is 50:1.
50:1
johnsons baby lube, trust me it works
That is 1.666 tablespoons.
25cc is 1/40 of a litre (there are 1000cc in a litre)
A guess-timate rule of thumb is 25cc per horsepower. So your snow blower would be about 7 horsepower.
where do i find a replacement gas tank for craftsman 17 25cc
40
Most lawn and garden equipment motors run about 1 HP for every 25CC ... so a 357 would be somewhere around 12-14 HP.
50:1 ratio. Or simply put - 2.6 oz of 2 stroke oil mixed with one U.S. gallon of unleaded gasoline.
