Default Jacobson 321 tune up parts?

I have a Jacobson Snowjet 20 that I need a tune up kit for.
It is a 321 motor. What is an REO motor? The ignition is a RE Phelon. The condenser number is RG3723 The point cover has model number T3440. Where can I find points and condenser for this engine? This is a real cool old machine and I am sure it will run!

Also can anyone email me a .pdf manual?
The one that is posted on flicker is just to slow. Thanks

In most cases if you just clean and polish the points and gap them at .020, it will run just fine. Worst case if the condenser is bad, any condenser from a briggs or small engine will work. The reo engine is a good runner. It turns counter clockwise. It was built by RE oldsmobile the car company. For the jacobson you will probably need to clean the carb, tank and fuel line. If you are careful you can reuse the old gaskets. In most cases these old things you have to make do with stuff you have. You can also cut new gaskets from material purchased from local auto supply or hardware store. Arlie

Exclamation Re: Jacobson 321 tune up parts?

REO also made a Techumpseh license engine, the last few years of production. They were usually painted metallic blue-green or semi-flat black. The horizontal was about equal to a H-30 Techumpseh engine, and most parts will interchange. The vertical was about equal to the V-35, and some parts would interchange, but not all. The vertical engine had different cowling andn fuel tank assemblies. The original 45 degree cylinder cast iron REOs are very collectable. Most used the engine camshaft as the output, running at 1/2 crank speed. These engines turned CCW at the flywheel. Some had a 4:1 reduction output, used on a 2 wheel tractor/mower.

The 321 is a good engine. The Sno Jet recommends 32:1 SAE 30 NON detergent oil as original mix. I have used 16:1 with modern oils in it, due to the use of E-10 crap fuel. The alky breaks down the oil, therefore the uprate on the ratio. 16:1 with the SAE 30 won't hurt either, but until the engine warms thoroughly, it will smoke a bit. Make sure fuel is thoroughly mixed before starting, by shaking the fuel can and the engine before starting and filling the tank. Once warmed, virtually no smoke. Remember - when setting the carb, do NOT make the engine sing like a bee when at full speed. It should break up, even double stroke, until a heavy load is placed on the engine. If you lake it sing, and load it, you will end up sending the piston out the exhaust in little droplets! (BOO-HISS)
