I am in Newzealand witch is about 90% farm, small tractors are worth a lot of money here as the people in the smaller Pacific islands want them, I can 100% say there are no parts in Newzealand, everything I have ever owned I have had to get them from overseas, 

 

 

I got the engine turning over last night but the exhaust valve was still a bit sticky, the sparkplug was so tight and when I got it turning it was cross threaded by the last owner, I will put a Hellicoil in it and I am going to remove the head as I think I need to clean and hone the bore and check that exhaust valve and seat, but I cannot find a head gasket, my wife is japanese ans she had a look on the net in Japan but sed its long obsolete.

That's a cool old tractor. It reminds me of the engines on the two wheel DaeDong and Yanmar tractors I saw while I was in Korea.

 

I don't know if this will work for the head gasket on this engine, but when I pulled the head off the old Briggs or Kohler flatheads, and didn't have a new head gasket handy, I'd spray it down with aluminum paint on both sides, let it dry, then install it.  Never had a problem with them.

 

Aluminum paint has aluminum metal in it, and apparently there's enough to make it work as a gasket.  It just might work for you.

I used head gasket spray on the old gasket in the end with good results, I saw a guy with an old Indian 741B who was using silver spraypaint and no headgasket at all

Recently i was wondering about the fuel for such engines. Would it run on ethanol? What could one use to substitute the kerosene or petrol kerosene mix? Would a mix of biodiesel and ethanol work?!!. Might be handy considering you can makre those two easily on your farm whilst biokerosene isnt so easy to make. Plus kerosene isnt cheap here anymore not to mention harder to find. Any thoughts folks?

I dont think it would run on ethanol with out changing the carburetor jets to much bigger ones, and you would need to drain the tank and dry the carb out thoroughly after each time you used it as that crap would cause major corrosion. it runs very well on 91 octane,  

 

ethanol is hard on rings and cast iron cylinders and it will destroy 2 strokes

[danhenry]

The cleaning part isnt an issue i think. Its only 15 litres afterall. The part about jets though could be the tricky part and corrosion. So if i can get the mix to 91 octane then it could be possible? In theory?

I must remember to keep the small petrol tank full, I forgot and it ran dry and it makes cold starts very hard

I gave the Triplex84 tractor I had to a guy down the road but I sold the rebuilt Kohler K301 motor and gave him a K341 for it, I towed it to his place with a sack barrow under the front axle behind the Hinomoto witch was harder than it sounds.

thats cool man. there is company's here that sell those off brand tractors like that. that's the biggest downfall is there is no parts for them.
