Help locating spring location on Briggs and Stratton engine (for lawnmower)...

Well, I was getting the old push mower ready for the new season and though I was grabbing some loose twigs behind the air cleaner and ended up pulling a spring out

From what Briggs and Stratton is telling me, the part# is 790849 and it's called a
Spring-Air Vane. My only problem now is figuring out where the heck I pulled it from. Here are two pics of the engine. You can see one spring in place. The other came from the same area. Any help would be appreciated.

All I see is dirt. LOL

If memory serves, the air vane has a spring that connects it to the governor. You probably need to remove the shroud over the flywheel to see where the air vane is.

You should be able to google your B&S model # and get a decent image of the spring location. Or you could tell us your model number and we could find it for you.

Maybe this pic will help?

XSleeper, I think you might be on to something. I posted two additional pics at the same URL. I do have a parts list with exploded diagrams, but I can't seem to find that spring in their drawings. The model# is

126T02

Do you think the area I have highlighted is where it goes?

Thanks,

ANdy

I agree with XSleeper, Pretty dirty.....

This should cover though;

Name:  Briggs Auto Choke Spring.JPG

This spring pulls the vane to close the auto choke, Once the engine starts the vane moves and opens the choke for normal operation.....

The spot where you put the question mark... that's where it goes. It doesn't connect to the air vane at all. It pulls the choke closed. The air vane moves the choke open once the engine starts.

Just got the spring yesterday and that picture helped a lot. It was exactly as you showed it. Just cut the grass and it worked like it always had. Thanks much!

Guess I do need to clean that engine. Any thing anyone would recommend to clean it?

Thanks again,

Andy

Hello Andy,


Good to see you got it going, Any automotive type engine degreaser and a water hose will do the trick.....
