really big pain

It was a part I had to have or I wouldn't have done it. The Spark Arrester part itself is fine. It's removing the old one and installing the new one that is the problem. I had to go buy a slide hammer because no one I knew had one, $33 more. Not that it's a big deal but I ruined the old one getting it out. The spark arrester does not just go in with a twist like in the video. I had to say a prayer and break out the dead blow hammer to pop it into place as I was about done with this thing. It's in now, works as it should and looks fine.
