Good morning,

I am in need of a diagram showing the location/placement of the governor spring(s) on a 1961 Briggs and Stratton 3HP horizontal shaft engine, Model 80252. Does this information already exist on the forum website somewhere? If not, could some kind soul please provide the information?

V/R,
Steve

This service manual should help. If you post the engines type number, I should be able to supply you with a parts breakdown.

You don't say if its fitted with a mechanical or air vane governor...! but the book that Rivets just posted should help you.

Rivets, EngineMan,

Thank you very much for your replies!
The complete model, type, serial numbers are:
Model is: 80252
Type is: 948097
Serial is: 6109150
Governor is: Air vane

Also, wanted to let you know that this engine is on a 1961 Craftsman Snow Thrower 18" (part no. 536.82125). It's a really neat looking machine that I would like to see running again. Any manuals on this machine would be great as well!

The engine manual provided by Rivets is very informative, but I don't recall seeing the spring connections to an air vane. It currently has two springs. A thin spring is wrapped around a rod and is disconnected at both ends. A second larger spring was laying next to the carb on the gas tank. How many springs is it supposed to have? Do either of you have additional diagrams that may help?

V/R,
Steve

Please check that type number, don't have anything with a six digit number. All the 80252 engines I find have a mechanical governor. I'm a little confused at this point.

Did some more searching and I did find your engine. You do have the correct numbers. Look at the parts breakdown and tell us the part numbers you are talking about. From that we will be able to tell you where to connect them.

Your sarcasm makes no sense, probably the best a counterman can do.

Appears to be a 200A governor, a 232A spring, a 209 spring and a straight link instead of a 201 link. See attached jpg image of my engine. Did I attach the large spring properly?

Yes, you have the large spring attached properly. The other spring which is on the rod should be attached as follows. One end will attach to the throttle in the same hole as the linkage. The other end will attach to the air vane. If there is no separate hole, attach it in the same hole as the linkage.
