Hi my saw blew up about a month ago so i have ordered a new meteor piston and jug, I'm waiting for it to come from the states. So whilst I have been eagerly awaiting the new parts I have been modding the muffler and practicing windowing the piston. what do you think. I am welding the exhaust tomorrow any hints or tips whilst i'm doing these mods....I don't know anyone in the UK who has been doing the mods like you guys. Whats the easiest way to wash all the aluminium particles off everything once its ready to re-assemble? I don't want to rush this project and would love to have a saw rivaling some of you guys across the pond!
