I have another question. If a saw is built, power ported ect., is that like having a car motor rebuilt, kinda like getting a new one or is a saw just done when it's done?
Most saw modifications are done to exsisting saw parts. So if the saw part is wore out, a good builder would replace it first, then modify it. If you send in a wore out old saw, it's goning take more money to make it good.
