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.

Yes, he is a kind soul......

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.

Ok, but if I insert the spring into the same holes on each end of the linkage, wouldn't that negate the effect of the spring?

That spring is there to keep constant tension between the air vane and throttle. It is used to help make sure that when the vane moves, the throttle reacts as quick as possible, no lagging behind.

I believe Rivets is telling you to replace (place) them here..! see photo red arrows.

Observation seems to indicate that when the operator moves the control from slow to fast, the larger spring should stretch while the smaller spring relaxes. When the operator moves the control from fast to slow, the larger spring relaxes while the smaller spring begins to stretch to help pull the throttle closed at idle. So if I insert the smaller spring in the holes suggested by Riverts/EngineMan, wouldn't the spring always stay the same length as the rod, thus having no effect on the throttle itself? Should the end of the smaller spring near the air vane, be connected e.g. 1) in the same hole as the larger spring on the air vane or 2) perhaps to the loop of the large spring near the air vane or 3) perhaps to some other spot which currently eludes me, in order to help keep the throttle closed when set to idle?

that spring is to eliminate binding of the linkage,if im not too far off,

Going by the parts manual....!

Yeah, I have argued with a few Briggs folk, that spring is pretty much useless.... I never worried about it or replaced it....

I shoudve read this more closely before I chimed in my 2 cents,( I welcome btw,when im told im wrong or full of it,im here to learn from the pro's)

I think I was way off,and none of you older guys will hurt my feelings in telling me so,

Maybe I didn't explain the use of that spring to well, I'll try again. That is not a governor spring, it is an "anti-flutter" spring and is not absolutely necessary. But, the spring connects at each end of the link in a hole near the link holes - one on the throttle shaft (on the carburetor) and the other on the governor arm. If you see no tiny holes immediately next to the linkage holes then simply insert the spring into the same holes as the link goes into. The purpose of this spring is to keep the tension tight between linkage and it's respective mounting points. I doubt if you'll notice a difference without this spring, unless you want it to run extremely smooth at idle.

Thank you all for your help. I got the engine running the other day. Everything was working well at idle and throughout the throttle range then all of the sudden it quit. Now have no spark. I replaced the points, condenser, and plug. Gapped the points to 0.020 and the plug to 0.030. I check the magneto and noticed one of the small wires coming out of the coil broke off right at the coil. No way to solder it. It is three leg magneto. Is there an electronic ignition replacement for the 291617 armature-magneto? If so, what is the part number?
