Tired old techumseh

[mpqualdie]

First time posting.

I have a log splitter that is pretty old. Not sure exactly I bought it at a garage sale and have gotten 5 good years out of it with a lot of tlc. It has a tecumseh hm100 motor. Last year the carburetor started giving me problems and I limped it through the winter. This fall it will not start and I'm considering a new engine vs. replacing the carburetor.

It burns quite a bit of oil and I'm constantly adding oil while working. The carburetor was pretty dirty when I took it apart and I cleaned it out. The spark plug was full of carbon, more so than last year.

Any thoughts from the community or suggestions for a replacement motor are appreciated.

Probably won't be a popular answer on here, but I used a Harbor Freight motor for a rototiller of mine and has done well for me. Also, using non-ethenol gas roll help in the future to not harm your carburetor. With my equipment I only use that, and stuff I store for periods of ti.e without using g I shut the gas off when done and let it run till the carb bowl runs out of gas so your not storing it with gas in it.

Hello T.,

These old cast iron engines were easy to rebuild as well. They were a minimal design with only a couple of crank seals and gaskets.

You might consider a light cylinder honing and putting a new piston kit or at least a set of rings in this Tecumseh.

The piston rings may be gummed up and seized in their grooves which would cause bad starting and oil bypassing in the bore casing high oil consumption

Hello T.,

The HM100 is a 10HP rated engine, but an 8HP would still do the job on a log splitter. These were heavy cast iron blocks and held up very well for a lot of years.

A lot of this depends on matching the crankshaft dimensions. Length, diameter and with or without a taper on the output shaft.

The bolt down dimensions may require that new holes be drilled to mount a replacement engine.

Being that old of an engine may take some adapting. I am still a fan of the old B&S flat head engines for applications like this. They were simpler to work on that the Tecumseh and lots of parts are still available for them.

Chinese clone engines are a big gamble and most compatible Honda GX series engines are just too expensive.

can you, or a knowledgeable friend rebuild this engine...? It shouldn't cost that much, or take too long, and well worth the effort.....

Perhaps this is not the place to post, but, I'm in NY state and have both an 8hp snow king tecumseh in a snow blower frame and 8HP B&S in a baker chipper. Both "ran when parked" due to unrelated mechanical issues.
