Question
gas is coming out of muffler while running

Answer
Are we sure this is fuel coming out of the muffler while running. 2 Cycle engines have a very hard time running without the proper air to fuel ratio mix. I have had this issue come into the shop before and it was actually water in the muffler where someone had left the saw outside.
Double check this issue and get back with me with a little more info about how the saw runs.

Thanks
