Old Briggs questions

#1
Hi. Picked up this old Briggs, just liked the way it looks. I Googled the model number, and it appears to be a 6 hp, possibly from the early 60's. It has spark, and seems to have good compression. It has a 1" ouput shaft, and has a centrifugal clutch installed, dont know what it was used in. Its missing a gas tank, and air filter. I would like to find both those items. I would prefer a gas tank that attaches to the motor. Not sure what I will ultimayely do with the motor, but want to get it running.
Anyone use one of these, or have info, or experience with one? Any changes neede if used on a minibike?
Thanks.

I have some neighbor/customers who still use those around their farms. They are solid engines. They are pretty simple and reliable.
It is a little bit large for some mini bike frames, but if it fits, it should be a strong one. I will look around for those parts. If I don't have them, maybe some of the neighbors have some. Start looking on eBay. Old parts come up on there often.
Be warned, Friend; Collecting old engines can become a habit that takes up a lot of space.

Yeah, I need to slow down with my new hobby purchases. Was looking for a motor for my first minibike project, and in less than a month, I now have 3 motors in my garage, and have seen a couple more Im curious about. I just got rid of a bunch of Volkswagen stuff (still kept some for just in case). Its easy to get caught up in the excitement.

The 6hp Briggs has become my favorite motors. When I first started working on one, I had all kinds of problems.
Getting the 6hp to rev high enough to operate the Tote Gote Climbaway clutch presented a couple problems: popping/running lean and excessive smoking. I sought out the old timers that raced the Tote Gotes. They seemed to be able to make them really run, this is what I found.
Popping and running lean: It seems the newer rebuild kits for the medium Flojet carburetors were designed for better emissions. Using a nozzle (emulsion tube) from earlier Flojets solved this problem. (Find the nozzle with only 5 digits in the part number).
Excessive Smoking: When these motors were filled to the top of the fill spout, there is too much oil in the crankcase. At higher RPMs oil is forced out the breather and into the carb, sometimes enough to foul the spark plug. The solution is to run less oil in the crankcase. I have only put one quart of oil in a 6hp. If using oil without zinc, I will add a couple ounces of zinc additive. I will also add a couple ounces of Lucas Oil Stabilizer. Change the oil frequently.

Another thing I really like about the 6hp Briggs: The cast recoil. It has a metal spool, not plastic. And it is able to be rebuilt repeatedly. No little metal tabs that break when bent more than once. Add to that: a special spring just to keep it from rattling when vibrated. I wish Briggs still made this recoil. It only was for the 6hp, 7hp and 8hp (and rarely a 5hp). Photo is a 5hp with the cast recoil...

I have 2 5hp briggs like that the one says 1975 I believe the pther one looks the same. They were on property when we bought the house. The old guy who owned the place was the local lawn wower repair guy.. 1773706571113.png
