Here re some detailed diagrams from one of my vintage Briggs 291691 kits. Matt

If your unable to get the needle and seat sealing properly, the Briggs part # for the carburetor kit is 291691, and they are still available from Briggs, and aftermarket. Most of the modern kits don't have all of the proper parts for these old carburetors. However, the needle and seats they supply usually work ok, although they require bending a tab down on the float, because the needle in the kits is usually taller than oe. The main body gasket in the modern kits work well, although the venturi gasket supplied in them is not the correct one for our carburetors, but most the time, you don't have to replace that gasket. If you want a kit with all the correct parts, you have to buy one of the vintage Briggs kits like this one. http://www.ebay.com/itm/NOS-Vintage-Briggs-Stratton-Carburetor-Kit-Part-Number-291691-/151732059572?pt=LH_DefaultDomain_0&hash=item2353ef7db4 Here are a few pics of the governor on a model N. Matt

I'm headed to work right now, but when I get home I'll get you some detailed pics of the governor assembly. A bad needle is fairly common on these little flowjet carbs. M

By the way. With your serial #113035, your Briggs was manufactured in March of 1943. Here is a link to the Briggs manufacture dates. http://www.asecc.com/data/briggs/data2.html Matt

You are a bit nutty Koen. Engine sounds solid, but, its flooding, and it sounded like it tried to over speed at the end. Have you tried twisting the fuel screw on the bottom of the carburetor in some? Also may want to check the governor. I really like it. Matt

The cranks on these kick start engines don't have a keyway Koen. They just have a hole drilled in them for the pulley set screw. Here is a picture of mine. Matt

That is awesome Koen, and I'm jealous! Parts for the Model N are still fairly easy to find if you need them. There is one thing you will need to take care of before running it for extended periods of time. Its missing the shield that wraps around the cylinder to circulate air all the way around for cooling. I like the early models like that one, as they use an oil pump instead of a dipper on the rod. I have a very similar engine to that one, except yours is a couple years older. Here is a pic of mine. Look forward to updates! Matt The last couple pics are of an original one, and it belongs to a friend of mine (Den).

Yes, I do like them Ian. I've always loved engines Ian, and thy're always my favorite part of any restoration project, whether its my Wheel Horse's, Case, or even my work truck. So, it just made sense to me to start doing just engines. That way, I'm always working on my favorite part of the restoration! That, and these old engine don't empty my wallet as quickly as some projects. Matt

I could very well be mistaken. There was an engine made by Cunningham here in the states back in the late 40's that was a near identical copy of the Briggs engines. The models were the Cunningham EA, and EB. From what I've been told (but I don't know for sure), Briggs sued Cunningham, and won, but those engines really were identical, with the exception of having a deeper shroud, and different fuel tank, and carburetor on one of the models. I'll try to dig up some pictures for you guys. Thanks Matt

Thanks once again Wristpin! It really is amazing how close these engines are to the old Briggs. However, I think they may have made just enough changes that they didn't need Briggs's permission to build those engines. Thanks Again. Matt I'll send you a PM here shortly. Matt

Thanks for those videos. That was really neat, but I will say this, he knows his Briggs engines about as well as I know my Suffolk (not very well) . The Briggs he was using was actually an early 40's Briggs WI. Let me know what you find on shipping, and I'm sure we could work things out. I don't know anyone with a Suffolk here in the States, and I would love to add one to my collection! I sure appreciate your help. Matt

I would love to have one! However, I'm a bit unsure how high the price would be to ship one all the way over here to the US. Do you have any experience with this? Thanks I tried searching for that YouTube video, but haven't been able to find it yet. Matt

Thanks, and they're really not to hard to find. Thats not my garden, its just the area behind my shop. I don't know what that is but, its indigenous to this area, and grows everywhere. While we're not in a drought right now, most years we are, and when all the grass dies, this stuff continues living. Matt

I really appreciate those pictures! If you could do me a favor, and post a picture of the PTO side of one of these engines, I would appreciate that as well. The first time I ever saw one of those engines was here on MOM, not long after I joined. I knew as soon as I saw it, it was derived from the old Briggs cast iron 5, and 6 cu in. engines. I don't know what kind of a deal Suffolk had with Briggs, but it was great to see this design continued in use after Briggs stop making them. Do you know what years these were in production for? I like the way Suffolk added a oil dipstick to the design, and they certainly have a completely different design carburetor. I would love to get my hands on one of those engines, but I don't believe any of those made it over here. Once again, I really appreciate your post, and I look forward to seeing more pics. Matt

Thanks Mark, I take that as a great compliment coming from you. You do amazing work. Matt

Hello all. I just finished up another refurbish on an old engine. This engine is badged Pincor, but was manufactured by Briggs. These were used on Pincor reel mowers, and had a large 2 speed gear box mounted to the engine. While Pincor did make their own engine, its thought that later in production they used a few of these briggs engine. I got this engine a couple years ago, but it was damaged badly in shipping due to the previous owner doing a terrible job of packaging it, before sending it to me. It made me so mad, I put it on the shelf, and didn't touch it for the last couple years. The first couple pics below, are the pics of what I supposed to be getting, but trust me, thats not what it looked like when it got to me. The shroud was smashed, a corner of the head was broke, the oil bath filter was missing, and it was just generally beat up from bouncing around inside of a box for 1000 miles. I finally got over it, and gave it the attention it needed. I replaced the missing, or badly broken parts. I then spent some time doing body work on the sheet metal to get it straitened out. The engine got a fresh set of rings, valve job, gaskets, and seals. It runs great now, and looks pretty nice as well. Here is a video, and a few pics. Matt

Your doing very nice work there. That's going to be one sharp looking Bolens! Matt

Yes, it did. I told Danny you said hi Neil. He thought that was pretty cool. I love all 4 of my kids the same, but its really nice to have one of them thats interested in this kind of stuff. If I'm wrenching on something here at the house, you can bet Danny is with me helping. I can tell you, it doesn't get any better than that folks! Thanks Nigel, I appreciate it. Matt

Thanks guys. I appreciate it. I wasn't going to talk about that, but I can tell you I won't be doing this again anytime soon. It was alot of work, and I'm not as young as I used to be, but it was fun. Thanks for the kind words. Matt

This is something I've been wanting to do for awhile, and I finally did it yesterday. I pulled out all my old Briggs Model N's, as well as a Model U, Model I, and a 6s, and ran ran them all at the same time (22 engines). It was fun, although it was a bit more work than I thought it was going to be. When this many engines are running, its difficult to hear the exhaust note of each engine so that I could get the fuel mixture set correctly on the carburetor. In this video, the newest engine is a 1952, and the oldest is a 1940. There was one engine (my lever start) that I flooded, so it wasn't running in the first video, but I did eventually get it fired, and showed it running in the very short second video. Anyway, here are a couple videos and pics. Thanks Matt

There is nothing that brings out the finished product better than a fresh set of decals. Looks Great! Matt

I'm sure you guys are getting tired of me filling this section up with my engines, but I just finished up another old Briggs, and I thought I'd share. Its a 46 Briggs NR6. It has the gear reduction cast into the block, and looks almost identical to my NR2. Its an old military engine, and it was in rough shape, and missing parts. Thanks to having lots of spare parts on hand, it was no big deal getting it completed. It got new rings, one valve, new gaskets, and seals. I did it in a lower gloss paint since its military, but I still like the way it turned out. Here are a few pics, and a video of it running next to my NR2. Thanks Matt

Thats fantastic news! That valve was in really bad shape. Was the seat still good? The engine sounds good. Matt

Thanks Alain. I to am glad they're up running again. Thanks Norm. I was very happy to get an NR6 in my Model N collection. Thanks to it, I'm one step closer to completing my Model N collection. Matt

I thought I'd post up a couple of my latest projects. The first one is a 1946 Briggs NR6 military engine that was recently given to me by a friend. It was in rough shape, but it was free, and I didn't have an NR6 in my Model N collection yet. The NR6 has a 6:1 gear reduction that is cast directly into the block. Its almost done now, and it turned out quite nice. I'm still waiting on my decals, and new tag to arrive. The paint job isn't that great, but I have to use rattle can paint on my military enges, because if I use a good paint, and spray it with my gun, they always turn out waaay to shiny. High gloss, and military don't mix! The second engine, is a 1952 Sears tagged Briggs NP, with a 3:1 gear reduction designed for use on reel mowers. Its all original, and I won't be restoring this one. I did pull the head, and the base, to clean out the 60 year old carbon, and sludge from the engine. I cleaned the carburetor as well. These are rather strange looking engines with their long gear reduction hanging off the side. It smokes a bit, but being 63 years old, it has the right to. Here is a video, and pics of each of the engines.
