When i get up there i will be running it without to get an idea if this is the issue, I just didnt get a real good look at the muffler before i left, so i cant say what it will need.
I hve so many of these sitting around, cant hurt to throw one in the toolbox (Heck, i might take one of my spares engines)
In the meantime, here's a few pictures of it, i forgot i had grabbed them, its an old straight bar Ryobi Scrub Hornet, with bull horns, no to bad a machine fro a ryobi, it belons to my Father-in-law to be, and it was his fathers before that.
I dont know if the throttle is original, seems like an old bike gear adjuster, it was pretty good while doing diagnostics though, as it alowed me to set the trottle in varios positions while making adjustments.
