Stanley chipper shredder pull cord is stuck. It has a back-up electric start, which also won't work. The engine sounds frozen.

My first idea is that the engine was shut off before the chipper or the shredder had not finished. First remove the spark plug. Next remove the covers on the chipper area and the shredder area. Now remove all material from both areas.Replace all covers, put the sparkplug back and try it.

Nice here a little suggestion

Small Engine Repair Replacing the Starter Pull Cord on Briggs Stratton...

Remove the spark plug and try again. If still stuck, then you may have a seized engine. You can unseize it with the piston facing up and using penatrating oil in the cylinder and putting the plug in finger tight and let it sit for a day or two, then remove the plug and try to pull it, if free, change oil before running, if not free, look in plug hole and check to see that you have even coverage of penatrating oil on the piston, add more if needed. There are a few real good videos on youtube, search freeing a seized engine and look at the ones for small engines.

I hope this is helpful for you.

Unfortunately, disassembly of the unit will be required to diagnose and replace/ repair the malfunctioning starter recoil unit.

I have the same problem. Did you get any help?

The drive belt may be the wrong size if there is no play in the clutch. I have a 10 hp, but there is a common manual for the 10 and 8. My belt is a 4L380.

it sounds like it is jammed up, take off the plug wire and look inside discharge chute for any debris.
