Hello all, I thought I would document the refresh of this little Briggs Model N here. The Briggs Model N was produced from 1940-1954. I have no idea what year this one is, since its missing its tag, although it is one of the latter models, as it has an aluminum head. The early models had cast iron heads. This engine is one of the industial series, as it also has a ball bearing for the crankshaft as opposed to the bushings most had. I have another N here for parts, and it only has a bushing. The guy I bought it from said he got it for a project for he and his son to mess with, but they weren't mechanics, and couldn't get it running. No wonder, the points were all crusted up, and they weren't opening. I got it in the mail today, and couldn't wait to check it out, so I tore it down right here at the house.
I opened it up to find it had a .010 piston, and the cylinder is beautiful with no ridge.
However it has some strange marks around the exhaust valve, they were doing something to it. I'l know more tomorrow when I pull the valves. I notice the exhaust pipe nipple is broke off in the block as well, but thats no big deal, I've removed many of those over the years. The crank, and rod have a marks you can see visually, but can't hardly feel with your finger, I believe the cranks will polish very quickly with a little 320 grit emery cloth. Sorry for being so long winded, the updares will be shorter.
Here are some pics.
