The smokin will go away with the next "batch of fuel".
I believe in the "If it ain't broke don't fix it", however, the industry standard has set, for environmental reasons, things that are not in the interests of 2-cycle engines, you should measure the mixture, 16:1 is about the max(which is an old Lawnboy setting). You will find it necessary to clean the carbon from the spark arrestor and stuff more often but things will last a little longer. Have a good one. Geo
