IMO, the reason for this is to cool the shaft housing which gets heated by the exhaust rather than to directly cool the lower unit.

It draws water up from the lower unit vents and ejects a small portion of it through 'witness' ports in the shaft housing and the bulk of it through the standard exhaust port in the lower unit. As such, there will still be an impeller in there which is likely in dire need of replacing. Remember that this is an air cooled head with a water cooled lower unit. The question is, if I do get it running, do I leave it JD Greene or go ahead and move on to Kubota Orange?

I'm going to start pulling it apart this morning, so hopefully I should be able to get somewhere with the motor. The engine block itself looks like a standard two stroke lawn mower engine. The fuel /oil mixture lubes the crank ,rod bearings, and cylinder bore as it flows through to the piston /combustion chamber. The carb mounts directly into the crank case.

Run normally after that and it should keep on going. New plug, 50:1 mix and run it in ina drum. Make sure you have a good coil and strong fat blue spark. Fill the cyl with kerosene to rinse it out.Р”В¬heck the rod bearings as well if they are fucked up you may have to replace them.

Use the flywheel to get it turning, nudge it a bit at a time, when igoes full circle, pour enough brasso in to wet the rings and work it over with the pullstart. Start by pulling the plug, lay the engine so that the plug hole is up, pour some penetrating oil into the cylinder and let it sit for a few days. He did have to replace a few small parts, but once tuned and cleaned out (and that was running it for 10+ hours each weekend for about five months) it ran with limited smoke and surprising power. A summer of properly mixed 93 octane fuel with the proper additives (we used PRI-G, FP-60, Viscon, and LE two-stroke oil because we had it and we knew that it worked great) (yes, with that additive list you can expect that we all work in the oilfield!) and the engine ran like new. If you will be using this over the summer a lot, mix up 5 gallons (measured) with the proper 50:1 mix and 1/3 ounce of PRI-G, for instance, and run the whole five gallons down.Р”Р„ number of years ago, a cousin got a similar engine and it was in pretty cruddy shape. My stock two-stroke advice is to make sure (measure, carefully) the oil and additives that you are using so as not to run too much oil. That and the PRI-G will gradually clean off all of the deposits and keep it clean. If if runs, I would suggest that you use a very high quality two-stroke oil from the start, ideally synthetic. This item is for sale locally, auction will be canceled if sold locally.If you can get it to start, a steady diet of a proper mix of PRI-G over the course of the year will clean it out nicely. 48lbs with no fluids, 31' tall, motor housing is 9' x 18'. Note: these are the dimensions of the motor not the crate it would be shipped in. I will ship to you but beware of E-Bay shipping estimates.Р’В I will bill you for the shipping and the cost of the crate (if any). Local Pickup available or I can deliver at my convenience to a nearby location. The motor stand it's sitting on is NOT included. You can't buy just one part for the 'buy it now' price. Price is set very low because I need the space in my shop and I don't have time to part it out. Purchased by my father in the 1960's and well cared for. I just don't have time to deal with it (too many Grandkids). Might be an easy fix or it maybe on it's last days. But one cylinder has very low compression.
