Yes, it is an aftermarket carb and the exhaust is from Black Widow Motorsports. A new air cleaner is on the way. Yes...I detailed and painted all the parts. I am not trying to suggest that this is an all original motor. My original post described it as "Does an a good running Tecumseh 4hp..."
It came with the Arctic Cat below. It was left in a garage for decades and was dirty and not running. The owner of the Arctic Cat wanted a little more hp so he decided to upgrade to a 5hp. He left me with this one and I was board so I wanted to see if I could get it running. So I cleaned it up, replaced the carb, the exhaust (the original was re-installed on the bike) , the plug, the head gasket, the oil, the fuel line, and added the tank that I had laying around.
In no way was I trying to represent it as "all original" but just as a clean looking, good running Tecumseh 4hp.
I may just keep it in my office as I think they look cool.
