Hi,
I have an MTD mower with a Briggs & Stratton 675 series engine. It wouldn't start today, and I may have pulled the pull cord too hard, it didn't break, it's only 3 years old, but now it seems that whatever it was attached to inside the mower, is not connected anymore, there's no resistance. I tried taking the cover off, but the housing for the pull cord assembly seems to be riveted on! If so, how do I get it off to get access to it?

Take the whole engine cover off as one piece and you can get to it.

(( cowboy up and get over it ))

You have to remove the shroud (engine cover) to access the recoil. Sounds like you broke the rewind spring.

Does the rope rewind back into the housing? If so, then I'd bet that one-way clutch is broken. I have no idea what it's officially called.

There are no clutches on this engine.

There is on the starter. It'll look something like this. Part #459 is a plastic starter pawl.

You may be better off just replacing the whole thing. Post a model # and type code.

Yeah, when replacing ropes on these mowers, I just drill out the rivets anyway, since it sounds like you will have to replace the starter anyway,
just drill out the rivets with a 3/16" bit. You might have to buy a cheap pop rivet gun, but you need one anyway.........

Thank you very much. I had no idea what that part was called, and was too lazy to look it up last night.

You have to take the cover off what ever you do. When you have the cover off, try turning the pulley in the direction it would normally turn when you pull the rope. If you feel resistance after five revolutions the spring is good and all you have to do is replace the rope. If you call the plastic area of the pulley, which has the starter pawls in, the clutch so be it. Before buying a new starter, check to see what the problem is. Repairing, even in a shop most times is cheaper.

This is the clutch I was referring to. I'm sure this isn't the exact part, but you get the idea.

Briggs and Stratton 393127S CLUTCH STARTER

That is a starter clutch, but it is not use on the 675 engines.

Really??? I taking you as the expert here, but then what the heck does it use to connect the recoil starter to the engine? Please don't get me wrong, I'm not trying to be sarcastic or confrontational, but I've never personally seen a recoil start engine that didn't have one of those on it. I've got either an 875 or 975 on an AgriFab tiller, I might need to know what that thing uses one of these days.

That style of clutch has not been used since the CDI ignition systems became popular. Today's engines use a starter cup which work in conjunction with starter pawls which are part of the rewind pulley. Only see those on the older horizontal shaft engines.

Yeah, that old clutch hasn't been used for many, many years. But there are still many, many real old Briggs still running strong out there too.

Oh okay, my Stihl has that. It's painfully obvious I have only had old equipment to work on through the years. :laughing: I do have that AgriFab tiller and a 5 or 6 year old Huskee push mower, I'll have to check them out.
