The Stovebolt Site Forums The Shop Area Engine Shop Suddenly, no power!

"It's never the carb"....well, except when it is.

I had a Rochester recently that I was not aware that the choke spring was broken, which allowed the choke flap to slowly close while I was driving the truck. One minute I would be driving along, and the next, my power was cut by 75% and it was puffing a little black smoke out of the tailpipe.

Of course, as many here will say, running a proper test and diagnosis is key, but never rule out the carburetor.
