I have a Sears DLT mower that has the 25HP B&S Intek engine. I have been looking for a troubleshooting chart for the engine. It is: MODEL  445777

TYPE      0129  E1

CODE     000731 YG

 

The issue is it runs great until I turn the PTO on. Then it starts cutting out, flooding, and all around runs poorly. Once you turn the PTO off, it takes a few and it starts running great again. I have no idea if the vales have been checked or the plugs replaced on this machine. I plan to R&R the plugs and set the valves soon. Just wondering if anyone else has had this issue with the Intek.

Seems like one backs off when under a load. Lots of black smoke too. Need to see a parts breakdown, wonder if the plug wires are getting bad?

   Not really the same as yours but I got a Jacobsen a few years back doing the same thing and it turned out to be the wires going to the clutch where frayed and wore thru so when you turned the clutch on it shorted the system and made the tractor run like crap.  just something to look for, good luck.

Hadn't thought of that! Worth checking out! Another thing I plan to do is check the battery voltage before and as it does this!

Not sure if I'll have time today to mess with it. Working on getting the Bolens LK running. Think I'll see about getting new fuel line, plugs and an air filter for it if I go for parts. Also an oil filter.
