Craftsman Tractor w/ 17.5 HP B&S Engine stalls
I was cutting my lawn yesterday (1acre) and got half way through when my mower began to loose power and stall.
I did the following:
New fuel, new fuel filter, new fuel line. Blew out carb and checked valves for any obvious play. Today, engine runs fine until I engage the mower deck. Checked sindles (removed deck) and both move normal. It appears that when it boggs down, I can see black smoke coming from the muffler, not a great amount but seems it is running rich under strain. Any other ideas, the mower is 10 years old and I stay on top of the valve issues with this tractor.
