Default 1970's Vintage Tecumseh Powered Troy Bilt Tiller

I'm looking for information on a Troy Bilt Junior Tiller I was given today. It is Tecumseh powered, I believe 3.5 HP. I can't find a model number anywhere on the tiller or engine. I would like to get an Owner Manual, Parts Manual and Service Manual.

The machine has a rectangular plastic gasoline tank. Side draft carburetor with a horizontally mounted cylindrical paper air filter with a metal filter housing. Everything appears to be original. I hope this can help identify the tiller's vintage. I was told it is from the 1970's.

Any good parts sources for these older machines?

check the shroud that goes around the flywheel for stamped numbers. If it a 3.5 hp, it will have a number such as H35-12345A or something similar. I would have guessed it was a 5 hp with a model H50-34567B. The model is the horsepower and the spec number tell us about all the different variations. Any decent Tecumseh dealer should be able to supply parts and a repair manual, and there are fellows here also

I will check the flywheel shroud again for stamped numbers. It may very well be a 5 HP engine. I saw some where on youtube a "Junior" advertised as a 3.5 HP. Anything is possible. Thanks for the info.

My dad has one, and it has a 3.5HP engine on it. It quit running so I told him to get a rebuild kit for the carby. It has run like a top ever since I rebuilt the carby.

Well, buried under some rust on top of the flywheel cover were the following numbers: H35 45593R SEP 62 47B. So it looks like it is a 3.5 HP Reduction Gear engine manufactured in September of 1962. After cleaning out the gunk in the carburetor, engine oil change, gearbox oil change and general TLC this engine runs very well (idle and full speed), starts easy and with a stable and responsive governor.
Now to track down a parts book and owner manual. What I'm finding so far on the internet is not that good. Any help is appreciated here. Pics to follow.

UPDATE. I believe this tiller engine was built in 1985, not Sept 62 like previously thought. I found what looks like a date stamp behind the flywheel "85". Plus it has solid state ignition. The engine is hard to start, it has good spark and a good carburetor. Plenty off gasoline getting to the bowl. But engine has low compression (50 psi). Disassembled it, valve seats and valves look good and blue check good. Cylinder wall looked OK but the rings have vertical scoring/scratches all the way around them.
Now the trouble is locating a standard 2.5" diameter ring set and a gasket kit. I know Tecumseh is long gone but is there anyone I can get rings and gaskets from?
Cylinder is now honed with a nice cross hatch, the rest of the engine is solid.

The scratches all the way around comes from dirt entering through the air filter. Double check the crankshaft conn rod pin for undersize and out of round. This is typical of tiller engines.

did not know tecumseh was gone! regarding the tiller itself there should be numbers stamped into the top of the gearbox near the rear. I will have to look at mine to be certain, mine may be different I think mine is the "Horse" model.

If you're cool with aftermarket parts, Rotary still shows some parts available for the H35.
