Stop in for a cup of coffee

Came out of the house this morning to take my wife to work and I found two surprises. Apparently one of my customers dropped off his snow blower. Read paranoid. And a kerosene heater. Upon my messages , he left me a text message saying he can't get his snow blower running or his heater on. This guy can never maintain or keep anything running. I'm always working on his small engine stuff. It's always the same. Carburetors need to come off and be cleaned. You think he would learn.
