Do you have an ATS or do you have a panel you will power with it?Muffler blew off my 12kw tri-fuel generator today.
I let it cool off and reattached the muffler. While it was cooling down I checked the oil (clean & full), pulled the air filter . . . and there was oil that blew up through the carburetor into the air filter? It runs, badly. Sounds like an old "hit & miss" engine. Valve head shot? That is the theory.
Called my buddy Chuck, who is INGO member IL CAVEMAN, he is having his guys show up at my house about 8am tomorrow morning with a brand spanking new 17kw Generac Natural Gas auto-start generator.
We got a 20Kw Generac a couple of years ago with an ATS. It is great. Runs everything we have.
