Stihl MS250 Porting-POP-UP-Muffler Mod- Dyno and Cutting***Dyno Gremlin Captured!!!!***

Porting the Stihl MS250 for the second time due to catastrophic failure. I modified the piston on the mill and ported the cylinder much the same as the previous. I used a Little Red Barn Pop-up piston that I found on Ebay as well as a Cylinder from Ebay or Amazon (I can't recall; I've had it a year or two).

PREVIOUS VERSON
Exhaust 98/ 164 total open
