I know the user name is misleading but I just picked up a WR426. I had the throttle stop cut down, put some tapers on it, and yanked the baffle out. My question: Does the stock silencer have a spark arrester? I don't feel like having to buy a new one. I like the DB level of the stock one and fine with the deluxe power. I live in Colorado and have to have a spark arrester in the woods.
