Photo Briggs & Stratton 5HP Engine

Well, here's my newest project, a 5 horse Briggs off of an old Lazy-Boy Deluxe tiller. I just need to build some skids for the engine, and it'll be up and running soon.

Exclamation Re: Briggs & Stratton 5HP Engine

2 things to watch on the B&S 5 HP - check the oil every time you fill the gas tank. The larger bore valve in block B&S engines tended to burn oil as they ran. You wouldn't see smoke, but they burned it noine the less. Don't let 'er run low! The second is that these engines tended to allow a little bit of crankcase vapor to get under the points cover. This in turn would cause loss of spark, due to corrosion on the points faces. Just clean with a white business card, and off you go! Nice find

Okay, thanks for the tip. I will certainly check that from now on. What do you mean under the points cover?

Exclamation Re: Briggs & Stratton 5HP Engine

If the engine is an older unit, it will have points and condenser. They are under the flywheel, behind a 4" round aluminum cover, held with 2 small self tapping bolts. If the engine has 2 wires leading behind the flywheel, then you have points. One is the mag feed to the points, th other the engine kill wire that goes to the shut off switch. If the engine is a later version with electronic ignition, then one les hassle to worry about.

Is this the same with the I/C series 5hp horizontal shaft industrial engines with the cast iron bores? Coz i have one of these.

I'm a firm believer in checking the oil before starting on any manufacturer's air-cooled engine EVERY single time. Air cooled engines run hot, and the oil is expected to provide some small measure of cooling as well as lubrication.... It's a good habit to get into.

Turns out Boise Small Engine doesn't have the coil I needed, so instead I went to MAG, and they had a Magnetron electronic armature, the one I needed! Here it is: (see photo)

Leave the points in! If you remove them, the points plunger will eventually fall out, thus making an oil leak behinnd the flywheel! If you have bought a conversion kit, sometimes they give you a steel plug to pound into the plunger passage. This is a permanant change. No plug, leave the points in!

Thanks. wait, what do you mean? just leave it how it is and don't do anything with the point/condenser assembly and it'll be okay w/out me putting a plug in?

Question Re: Briggs & Stratton 5HP Engine

Hey everybody. I've got one quick question about this engine. What is a normal operating temp for these engines? Mine runs pretty warm, but that does not surprise me considering it is air-cooled. That was to be expected. So, I picked up an IR thermometer, and I am going to see how hot she runs. Anyone know what the "ideal" operating temp for this engine is?

GOOD JOB ! It's good to see that there is another "Stakker" adding a "Classic" aluminum Briggs to his collection. Many people don't stop to think that the first aluminum Briggs engines have reached the 60 year mark.

I'm totally dedicated to the post 1949 aluminum designs

It's good to see young people take interest in antique/classic air cooled engines. I too, was around your age when I started collecting and taking apart small engines (that was around 43 years ago) ! I still have that "small engine bug" , even after all those years

I'm guessing that your engine is late 60s - early 70s, but if you give me the numbers on the side of the shroud, I can tell you exactly when it was made..

Feel free to take a look at my Photo Album to see my "Aluminum Collection"..

Keep up the good work, and one day you will probably have a great collection to take to shows with you. Somebody is going to have to "carry the torch" when us old timers are gone

Don't under estimate todays Briggs engines, that's the same thing that "we" said when I was your age, and today those very engines are antiques/classics. The new generation of engines will find their way onto a display stand 50 years down the road and us old timers are counting on you to make sure that happens !!
