You can go to Harbor Freight and get a $100 212cc Predator engine brand new or you can look around for other options. Other choices would be more expensive unless you go used, but some people prefer to keep them more original. You could probably find something used for around $40 - $60 if you look around on craigslist.

If you got lucky and the rod didn't crack the block you could just clean the crank up and put a new rod in her and put it back together.

Hi Malibu,

there is a fine Info-site which helped me in the past two years to get informations on my Ariens ST 832

The Ariens 1960's and 1970's Sno-Thro info site.

maybe that will give you infos to type, equipment an date of manufacture for your sno-thro.
Good luck while repairing.

Greetings from far away Germany

Markus

I'm rebuilding a Tecumseh H60 6-HP now that threw the rod. It actually did crack the block behind the starter. Brazed it up with some Aluminum brazing rods and a LP torch, seems like it will be good.

It's sitting on my bench waiting to be finished. Came out of a '60's Craftsman blower given to me from a neighbor. I also bought new rings some gaskets and seals will be into the whole blower for about $50.00

I did it to keep it original and I like old stuff.

It's $100 for a predator (pull-start), $150 for a Chinese universal snow engine(e-start) and about $170 for an LCT snow engine (208cc), prices go up from there to about $320 for a 420CC.

Some Briggs engines might still be found new but expect to pay a premium...If you want Tecumseh H engine, you'll have to go used.

welcome to the site Malibu. The used tec's are out there (just sold a 78 complete blower for $100- not the norm) but you got to watch cl several times/day and move fast if it is good deal. Some other things like tillers, ect might have a motor for you too..out of season so might get lucky. I've seen some tillers where a tec motor was put on , so all you'd need to do is switch the carb cover stuff over- most though have B&S on older ones. Just saying used is option- but not as easy anymore.. takes more looking to find a running one than few years back. The HF motors better option by what I hear they are good. Just not original.

To get your correct connecting rod we would need the numbers stamped on the top of your engine. Probably something like H50-xxxxx SER 1234X. To be successful you will have to know that the rod breaking didn't break anything else in the engine.

The rod is the bearing...You're going to have to inspect that motor really well, If the cylinder is damaged you'll need a piston and a bore. Lots of times the rings wear, and then lots of unburnt fuel gets into the oil, weak or low oil causes catastrophic failure.

I checked crank journal and cylinder look good piston also looks good probly a good idea to change rings ,,,,now I'm also going to need torque specs for connecting rod and the top cover that covers the valves I'd like inch pounds as I have the torque wrench

If you like to have a hard copy while doing the inspection and or rebuild that Tecumseh manual is usually available from a library.

Well on further inspection on the motor I found a chipped section on lower part on the piston side skirt so it looking like I'm getting a preditor motor ,,,, by the money I would spend on a rebuild I'd be more than half way of the expense on the 212 cc preditor

Any time you dig into an old blown motor you are likely to exceed the expense of a pull start predator. This is true even if you can do the machine work yourself.
