Yes, I would get rid of that gas and start over with a 24/1 mix with a good brand TCW3 outboard oil. The Poulan oil may cause excessive smoking, but that motor will smoke anyway with a 24/1 mix.. so that’s normal. You will need to run the motor full throttle and adjust the high speed needle FIRST, then idle down to a trolling speed to do the low speed needle. Glad you got it fixed!
