Hello, and welcome!

Look on the tins that cover the heads. If it's an ohv engine, look on a valve cover.

On some of the older Briggs twins, the model, type, code is stamped on the side of the small end of the blower housing. A magnifying glass is certainly useful.

On some of the older opposed twin cylinder engines, the numbers were stamped into the cylinder covers that wrap around the cylinders just behind the engine shroud, otherwise they are stamped into the covers on the heads or riveted to a plate on the blower housing.

Is this engine stand-a-lone or, is it on a piece of equipment ?? In many cases if we can ID the equipment(product, model, serial, etc), we can find what engine is on it.

Call Briggs

Describe your engine to the Briggs Answer Center at
1-866-927-3349
They should be able to give you the base model number sufficient to order parts.

Maybe this link will help in locating the number.

How do I identify a B & S engine?

glenm.this is a stand alone engine i picked up free in good shape..i do not know what it was on..im thinking not a mower because of the horizontal shaft..i know they use them on mowers to but there usually vertical shafts.i still have found no info on the engine..really discourageing steve

maybe a picture would help. also like glenM said call that number and describe the engine. hopefully they can help. are they any holes on the engine like there might have been something attached like screws or rivets for a plate. sense its a I/C (industrial/commercial) engine it might have been on a generator or chipper etc.

Take a look at the image in the link posted below, it's from an opposed twin cylinder, horizontal shaft Briggs & Stratton engine. Look for numbers stamped in the cylinder covers ref # 306-1 & 306-2, or on the cylinder covers ref # 308-1 & 308-2.

If these parts are missing off your engine, then that probably why you can't locate the numbers, or perhaps the ID tag was removed for some reason.

Briggs ID'd

Due to number of L-Head Briggs twins I've received to repair last couple of years, the 1 repair manual I have is for these engines.
The oil filter clue you gave, plus being horizontal has isolated the basic models, according to the manual, to the following:
400440
402440
404440
422440
My experience with 18hp models are 42 cu. in.
My best guess is the 422440
Enter this value at briggs site
Manuals, Parts List & Wiring Diagrams - - Briggs & Stratton
1st file is the owners manual, the following(all the same) will be the illustrated parts list.
hope this helps,
thanks,

Great detective work GlenM, I was just fixing to take a look through my Srv. Man., now I don't have to...

Most parts are interchangeable within the various type numbers, the only differences may be in the type of controls, fuel pump, ignition and perhaps carburetors used, but most of this would be fairly easy to determine.
