Default Clinton model B1290 info needed / no pictures

Well I was out in my old shop moving my stuff in to my garage that has more room and is a little warmer when I found another Clinton small cast iron engine.

Serial # 7854210B.

Model # B1290-1238.

Orange in color. Recoil starter, fuel tank and Carb missing. Has good compression, but no spark. Has two levers with plastic orange knobs above the blower housing. Odd three sheave pulley and linkage on the PTO side of engine. Oil in crankcase a little dirty. J8 spark plug. I have not found any information on it yet. Any ideas as to size, h.p. or time frame when it may have been made ? This engine was given to me about a year ago from a guy in Donald Oregon. He had no info on it. Sorry I am unable to do pictures at this time.

Nice score. I have one of these on the to-do list myself. It has a broken camshaft but I have a new old stock one ready to go in. It's complete but the carburetor and gas tank are off. What are you looking to get pictures of? I also have a later 498 which is basically the same engine.

Your engine produces 4 hp @ 3600 rpm, 3.6 hp @ 3000 rpm, 2.9 hp @ 2400 rpm & 2.2 hp @ 1800 rpm. Bore is 2-15/32", stroke is 2-1/8". The recoil was optional, it may have been rope start. I can't really give you a time frame but my parts list is dated March 1961, superseding a December 1959 version. Looks like your variation (1238) is equipped with a valve seat, roto-cap and Stellite valve on the exhaust side.

Here's a parts list for you, courtesy of Larry Rarus' Clinton site:

Hope this helps.

EDIT: Read your title wrong, thought you were looking for information & pictures.

I have a Clinton model 498 and will compare the two of them. I found Larry's Clinton site right after I started this thread. My blower housing has 4 studs on it to mount a recoil setup. I spun it over using a drill to check for compression and spark. I don't collect Clinton engines, but I now have 9 of them. Of the 9 engines, I only bought a model 414 and a model 498, the rest were given to me. So far of the 9 engines I have ran 3 of them and they only needed the points cleaned. I wish I could do pictures, but don't have a proper camera at the moment. I have lots of books and manuals on Briggs engines, but nothing on Clinton's except what I find on the Stak and the web. Thank you for the information.

I think you're going to have a tough time locating a recoil. The early Wheel Horse crowd has likely snatched most of them up.

I prefer the larger Red Horses like your 414, but I've managed to acquire several of the smaller Long Lifes. I have the previously mentioned B1290 & 498 along with a D700. Clinton is my second choice after Wisconsin.

If you're diligent enough, you can often pick up a Clinton Parts & Service Manual for ~$30 at a certain auction site.

I have a engine that I have not ran yet that has a recoil setup on it that I can use if it turns out to be a core engine. My 498 engine and one other also have recoils on them, but they are both good runners. What did the early Wheel Horse tractors use for a engine ? I also have another engine that has a complete rope start setup on it, but is buried at the moment, but looks like the other engines far as size. I was working on the B1290 model tonight trying to get the pulley off the PTO side. It has a chunk missing out one of the sheaves. I have also started to clean the engine so the other engines will quit teasing it.

As far as Clinton engines go, Wheel Horse RJs used both the B1200 & B1290. I don't know what model variation(s) they specified. They also used Briggs and Kohlers.

I am learning about garden tractors watching other sites. Engines I have, tractors not yet. I would like to find a old something or other to use some of my engines on. I got my model 414 Clinton from a young man that was working in a small engine repair shop along with a Briggs model 23. The model 414 had a home made intake manifold with a side draft Honda motorcycle carb. Other than take intake and carb off and plugging up future spider homes, it sits on the floor awaiting it's turn. I must say again, I am impressed with the build quality of cast iron Clinton engines.
