Unhappy Craftsman help...

Have a 17hp, 42" Craftsman ride mower with a B & S engine that has serious problems. When running in fast idle it has a miss or dying out sound. When idle in slow it is more noticeable. Sounds as if it is going to cut off. I have replaced the spark plug but notice no change. Any advice would be greatly appreciated.

Would the dying be accurately described as a "surging", from almost dead, to revved up, then back to almost dead, etc...?

Yes, its like a surging sound. It does not cut off...but when lever is in slow it sounds like it could cut off.

Ok, surging is caused by fuel starvation. You'll need to remove the carburetor bowl and have a look in it. I'm guessing there's junk in it that needs to be cleaned out. Get a can of carburetor cleaner and clean the bowl and the carburetor area enclosed by the bowl and see if that gets it straightened out. If not, you may have to remove the carb and do a more thorough cleaning.
