It has FB4209 stamped in the block. The base is in perfect shape, but no carb. The pot metal flywheel, and backplate are also in perfect shape, no issues. Somebody had made a tin shroud to put around the fins for better air flow, so there is about 8 or so really small holes drilled and taped in the crankcase where they attatched it, would be very easy to plug them. The only other bad thing, is the head isn’t correct, somebody put a 4 bolt head on it, when the block is a 2 bolt, so they used one of the original holes in the block, and for the other three, they put little gobs of weld on, so they could drill and tap them for the other 3 holes, I think that would also be real easy fix, to take the head off and grind those welds off, and plug the holes. Finding the correct head will be your biggest problem. The last thing to say is, the cast iron flywheel has holes drilled in it as you can see, and there are cooling fins inside the flywheel, The holes, and fins both are most definitely not homemade, they are factory done, being an FB, I’m sure it was one of Briggs ideas for better cooling. The holes being machined on angles, to suck air in. The fins inside the flywheel are machine bent and made, nothing about it is cobbled. If you zoom in on the picture you will see it is a factory done job with the holes and fins, and the rivets that hold the fins on, with original paint overtop of the rivets. Very restorable engine, especially since they are repoping the peace pipe carbs. Feel free to ask questions, these FB’s don’t pop up for sale every day! 7 DAY LISTING – NO RESERVE!!!
