Chainsaw Repair

On my saw I opened up the muffler a bit more and it seemed to run better with the larger opening but to do it over again I would stick with the original mm. larger opening is just a slight increase in power and a drastic increase in noise. I enlarged the opening more and clamped the muffler and cover in the vise. Heated the deflector with a torch and used to ballpein hammers to form the deflector larger giving more area to the exhaust outlet. The original piece I removed is there to show just how much larger the opening is from what I normally do
