Briggs and Stratton - SAE socket sizes

[88nightrider]

Since I live in Norway most of the things here have metric fittings and bolts. So in general tools in SAE sizes are not so common here. Granted that some of the metric sockets do fit some of the SAE sizes...
The only things I have personally encountered that use SEA fasterners are some of the old tractors we have here, and my 1987 Ford Sierra (a mix between metric and SAE).
For those we have tools that fit, so no problem.
But the Briggs engines in general use quite a bit smaller tools then those we got here.
One of the sizes I have had to "improvise" with is the one thats on the bolts that hold the ignition coil in place on my 3HP...
So if anyone has a list of the socket sizes generally used on Briggs and stratton engines 3HP to 8HPD) I would be gratefull.

here you go:
It's a general B&S Hardware guide, not engine specific
but I assume it covers most if not all the bolts on your engine as well

http://www.briggsandstratton.com/~/...ions/engine/pdfs/engine_mounting_hardware.pdf

it not only tells you bolt sizes and their wrench sizes (SAE and DIN)
it also lists some torques

Now I know roughly what I need
So on Friday I can get to a store to see their selection of SAE size tools

Thank you Alexander

I would just get a deep socket set:
You would probably cover your bases with:

5/16"
3/8"
7/16"
1/2"
9/16"

Not sure about the flywheel nut size, that's definitely bigger.

You forgot 1/4".......

 

[KartFab]

Your right. There may be a few bolts on the carb that need 1/4" from what I can remember they also have different heads (torx? Flat, Phillips)

 

[88nightrider]

Thank you everyone
So
1/4"
5/16"
3/8"
7/16"
1/2"
9/16"
should about cover it all?
Torx, flat and philips should not be a problem

Not sure about the flywheel nut size, that's definitely bigger.

As I have yet to take the starter ratchet clutch off the flywheel I haven't seen the nut.
But I did find this on ebay:
Go Kart Racing Mini Bike 4-5hp Briggs & Stratton Flywheel Starter Ratchet Clutch
Is it a special nut that holds the flywheel?

 

[qtband]

I don't think so. 5/8 or 3/4 or something a little bigger. I'll try to check mine when I get home tonight.

The starter ratchet is what holds the flywheel on; those tools are to remove the starter ratchet

13/16 for the spark plug. hold the flywheel with a wrench and use a hammer and a piece of wood and smack the starter rachet assembly counter clockwise.

Might be right I have a selection of different sizes plug sockets that have yet to let me down.
But thank you

As the starter rachet assembly I have on my engines looks to be made out of plastic. Doing that won't hurt them then?
And I wont break off any of the cooling finns either?
Again, thank you

U can put some rope in the spark plug hole and turn over the motor until it locks up as well. Your starter assembly should be metal, with a plastic cover on the front and typically a metal mesh bolts over that with 2 1/4" or 2 5/32" bolts

I'll look into that when I get home to my parents on Monday - Tuesday (ATM I'm only at my apartment in the city in the weekends).

Thank you
