I recentley picked up a couple of David Bradley engines. Both are Briggs Model N's with the mechanicle governors, but one is a rather rare engine, that came from the factory with aluminum tins. Aluminum shroud, heat shield, and starter cup, which are the rare items. It also has aluminum head, oil pan, and intake, which are pretty common. The aluminum parts are very flimsy, so most of them are long since destroyed, especially the starter cups. This engine had already had its starter cup replaced with a steel one, but I recentley aquired an aluminum replacement. The original Sears 500 id tag is in pretty rough shape, so I'll probabally have a reproduction briggs tag made for it, since I dont know anyone who reproduces the Sears tags. I'll keep the original with the engine. I've already got the aluminum tins cleaned up, and cleared. They're not perfect, but still look very good for their age. Here are a few pics. Thanks

So does it run or you have to rebuild first? I don't think they look that bad (the tins if you can call them tins) for being 60 or so years old. Bet there is a few DB guys that would love to have that engine. Thanks for the pics :thumbs:

The cylinder, and crank are in great shape. It had good compression as well, but it will still get honed, new rings, valves lapped, clearances set, new gaskets, and seals. All my engines get that. I figure they deserve it just for surviving 60+ years. I'll be starting a thread on the little Bolens NPR6 here shortly, as its coming along well. :thumbs:

 Well, I decided it was time to give an update on this engine. Being that this engine is kind of unique with all of its aluminum components, I decided that anything on it made of aluminum would only get cleared, rather than painted black like Briggs did it. I know its not original, but I like it. I got the engine rebuilt, new rings, lapped valves, new gaskets, and seals. I also got it painted, and ordered a reproduction ID tag for it that should be in before to long. Here are a few pics of what I have so far. :thumbs:

I guess I should of looked at this thread first before I posted in your other one.

 Its pretty well done now. I'm still waiting on a new throttle rod, and the new ID tag to come in, but thats about it. :D  It really stand out sitting next to my other engines. I'll try, and get a video up of it running soon. :thumbs:

 I got my new ID tag in for it, and a set of the factory type rivets to attach it with. It looks great. I couldn't find anyone who reproduced the sears 500 type tag, so I just had a Briggs tag made for it with the correct numbers on it, and I'll attach the original tag to the wooden base I have the engine bolted to. I also picked up a mint condition clear united oil bath air filter the other day, that I decided would look great on this engine. I'm still waiting on a throttle link to come in, and then I'll post a video of it running. Thanks
