1946 Briggs NPR6 (lots of pics)

[bowtiebutler956 649]

I still haven't got another to fix up yet, but I have picked up a few more antique Briggs engines. It seems like they're multipling like rabbits every time I turn my back! This one is from a Bolens Power Ho. I bought this one because its gas tank has a thu rod fuel shut off, which none of my other Briggs engines have. It also has the the long S bend pipe going to the air filter. Upon opening it up, I found it had alot of rust pitting on the deck of the block, paticularly around the exhaust valve, including some on the head gasket sealing surface. Strangley enough, the cylinder was beautiful with no rust at all, or ridge. I gave the cylinder a quick hone to break the glaze in the cylinder. I took it to the machine shop to have it decked, and the exhaust seat cut. There is still some pitting on the deck, as I told them only to remove enough to give me a cleand head gasket sealing surface. The gas tank was pretty rough too. I had to open it up, so I could remove the dents, and rust. I had to replace the threads for the gas cap as well. I then resoldered it back together, and primed it. I now have the long block assembled, and painted. I know its not , but its what I've been up to lately.

what a lovely little engine

nice job

what are you going to use the engine for?

[bowtiebutler956 649]

I just enjoy restoring these old engine. I have 9 old Brigg engines right now, rangeing from 1939-1952. I am planning on building an old air compressor out of one, and maybe an old go kart out of another. I would really like to get an old Bolens, and David Bradley walk behind garden tractor that these little engines originally came on.

Are you sandblasting the entire engine assembly as a whole Matt?

I didn't sandblast this engine Craig, as the block wasn't very rusty. After disassembley, I soaked it in my 5 gal. bucket of carburetor soak, and just rinsed it with water when I was done. I did sandblast the head, and I still have a few pieces of sheetmetal I need to blast.

Great work on the engine.

I've had a few old Briggs like that. Had that exact engine on a Bolens Super Hoe w/sickle bar mower. It still ran great but sold it a year or so ago.

Below is a pic of a home built gocart built in the 60's that I recently picked up. Near as I can figure, the Briggs is a 1962 Model 5S. The sheet metal is just galvanized tin with a 50's Chevy hub cap for the nose. Bought it from a guy who's dad had built it for him. Having trouble finding a non-keyed, 5/8" shaft, variable speed belt drive centrifugal clutch for it.

Those engines are pullin' little suckers.

Very cool old kart! Your engine is definitely a 5s or 6s, but its older than 62. Both the 5s, and 6s last year of production was 1957. If it still has its tag, you can get the serial no., and go to ASECC.com, and find out what year it is. Very nice!!

Looks like the cart is fitted with a 603 steering wheel.

I got the rest of the engine painted yesterday, and the paint turned out great, all except the gear reduction box, which had a bunch of fish eyes in it. I guess I didn't clean it well enough. Oh well, I'll strip it, and repaint. Here are a couple pics. One of the pics is a little blurry, but I'll post some better ones soon.

Excellent work. It's great to see the old Briggs still running. :)

[bowtiebutler956 649]

I've been busy the last couple days, so I haven't done much with the little Briggs. However, I did get the decals in the mail, and I had to put them on! I love putting new decals on restored old iron, as it really makes them stand out. Here are a couple pics.

There's been a couple Allen Bradleys for sale on cl in northern Mi for about 6 months now. Nice work on the engine! :thumbs:

[bowtiebutler956 649]

I finally got around to taking a video of it running. It runs fantastic, and I'm very happy with it.
