Default Briggs 10T502 Service Manual ?

It's been a while since I posted on the forum, so if my post is in the wrong place apologies.

I've just bought an old-ish mower with a Briggs Engine that's not been run for a while so I'm looking for the service manual & hoped someone on here would be able to help. I can get the parts list & user guide from the Briggs site so it's just the service manual I need.
The full engine number is: 10T502-0188-B1

I think the manual reference number is 270962 which looks to be a generic L Head manual, if anyone has a copy they can share it'd be much appreciated.

Thanks

Just googled it and a pdf link popped right up.....
scratch that. That pdf just refers to that number. Everyone seems to want to sell it.

Yep, that's what I found too. I'm hoping that someone has a working link, or a copy that they could share with me.

Thanks to Bruce for his help.

The engine on my 'new to me' mower has the most fearsome kick-back I've ever known on a rope pull / recoil starter. Hopefully, I think it's due mainly to my running it without the blade. I've since read that it's not a good idea as the flywheel is light on mower engines to make up for the blade weight.
I've ordered a new spark plug as I think the old one is faulty and will re-attach the blade when the plug arrives before trying to start it again.

This is my first 'modern' vertical shaft briggs, after having a couple of horizontal shaft engines from the 60's & 70's, never too late to learn!

If you are getting kick back, I'd yank flywheel and check key isn't partially or completely sheared.

Yeah, that's the next on the list if re-fitting the blade doesn't do the trick. I took the blade off to check the roller drive belt & left it off while I cleaned & dried the belt cover. In addition to the kickback, the engine hunts quite badly, but again maybe the blade affects that.

I "fixed" many mowers by tightening up 1 bolt, the blade needs to be on. Also get carb diaphragm 795083 (or 795803 I don't remember) it will need replaced. When you remove the carb from the tank, you will see at the back where the diaphragm has "puckered". B & S needed another screw back there. This is a very common problem with those primer carbs, needs fixed every few years.

A quick note to say thanks to all those that responded to my thread. I put a new gasket & diaphragm in the carb, refitted the mower blade, put in a new plug and it started straight away without kickback & ran without hunting. Time will tell if the cheap diaphragm lasts the season, but at least I know what to look for if it goes again.
