ordered a refurbished chainsaw from vminnovation the other day and went out today, bought new 1 gallon gas can, filled at gas station to 1 gallon line then added the 3.2oz full syn that came with saw. Followed directions to start and started but sounded like was stumbling? Best way to describe it is not very smooth, surging then almost dying... ran about 15 sec then died out, pulled again and starts for sometimes few seconds but never more than 15 seconds. Nice amount of white/gray smoke as well. If I try pull trigger it instantly dies and one time I pushed in on primer bulb and rpms surged but again slowed and died. Tried pulling spark plug and was all black so cleaned it off with some starter fluid as well as sprayed inside of hole and shook it upside down...same results. Again took apart and this is what I see. Also took off what I assume is the muffler. My first experience with a chainsaw is not going very well lol. Thanks for any help.
