Just signed up today to hopefully get help solving a problem with my Stihl MS250 chainsaw. Last fall I scored the piston by pushing the saw hard with a dull chain. I cleaned the cylinder and put in a new piston. I replaced my crank seals and pressure checked for air leaks. The engine had no air leaks. I also replaced my intake boot. Once I got it all back together the saw would pop on full choke and then run strong for about 3 seconds on half choke and then die out. Thinking it might be my carb I bought a replacement carb and installed it, along with a new carb to boot, gasket. Still have the same problem. I'm going to replace my impulse tube now but running out of time to get this saw working and asking that anybody, make any suggestions as to how to solve this issue.
Thanks in advance.
