Here is a port job I did on my Stilh MS290 Chainsaw (2 stroke). Haven't gotten to cut anything with it but along with a muffler mod she should have some good power now. 1st picture is intake, 2nd is exhaust. #brapp

Looks good man. I also just to took the 50ccm 2 stroke engine of my Moped apart, fixed the transmission, cleaned it all up, and put it back together. It’s such a pleasure to see the difference and it breaths very freely now.
