The perfect gas oil mixture for the jonsereds 49SP is 1:40 !
Check your user manual or the dealer that sells your brand. The mix could be 1:32, 1:40, or 1:50.
40 to 1
For 2-cycle oil it is 40:1 and for 30 weight auto oil it is 25:1
That is 40 parts gasoline to 1 part oil.
yes,mix it 32-1 or 40-1 ,make sure the oil is 2-stroke for injection or pre-mix
40:1 means 40 parts gasoline to 1 part oil. So 40 OZ. of gas to 1 OZ. oil. If you wish to mix one gallon of gas, 128 OZ, you would add 3 OZ of 30 weight non-detergent oil (30wt ND), also sold (with green dye added, at a premium price) as "two-stroke oil."
for my 1982 Cr125 the gas mixture is 40:1... not positive if its the same for a 250... but my suzuki 1991 suzuki 250 is also 40:1 so its most likely 40:1...
