Currently lawn art. Need practically one of everything. I just want to learn enough about it to acquire the correct parts.

Well, you are in luck. Most of the parts you will need are being reproduced. Click the sponsors link at the top of the page. Several there have the parts. Start oiling everything now and let it soak while you are learning about it. Once you start on the project post it over on the main engine forum, you can post photos there also. Search that forum for M threads and you will find good info.

Welcome to the stak. Be warned that working on these engines is addictive. You can't stop after getting one running, you will have to have another. Have fun!

A few quick facts: Gasoline only engine. Used a WICO EK mag for ignition, which dates the engine later than 1923 If the S/N is readable, you can date it exactly. Many parts still available, check with H&M enterprises IHC M parts list for starters. He has a parts diagram on the page.

Was the engine turned on end as pictured when you found it? If it was, then severe rust inside the engine may be a real deal breaker. If the engine was on its base, as if being used, then you have a chance at restoration. A picture of the top and magneto side of the engine will help, as well as a more distant one of the head, so we can tell you more, and identify missing items for you.

I wrote an article for The Gas Engine Magazine Sept./Oct. 1984, about the restoration of 2 IHC M engines (1927 and '28). You can either get a back issue from GEM or view it on line. The article was named 'A tale of 2 engines. I included pictures which may help you identify parts. have a look at H&M Enterprises IHC M parts list too - he has a diagram on the page. H&M is a sponsor here on the Stak - look on the sponsors page for his site.

Thanks guys! The serial number plate is totally unreadable. If I get the piston freed up, I will have a big order for H&M enterprises!


My main issue was identifying the correct magneto since they are pricey.
I already have the wrong manual that applies to a low tension machine.
It's only been up ended to fill the cylinder with oil.
The cam cover is cracked. The exhaust push rod is bent and cracking at the threads. The fuel pump, governor linkages, magneto and it's lever, spark plug, choke plate, oiler, fuel tank cap, fuel lines are all missing altogether. Not much left of the fuel tank. I'm sure that there are other missing items as well.
I'll try to get some better photographs later.

Here's a few more.

Great article. Good to know I'm not the only one with a destructive childhood. Also good to know it is probably salvageable.

I'll offer you a link to a video series from Shopdogsam on youtube. I learned a great deal of information about how these engines are put together.

one great thing about these engines is the cylinder is replaceable so if the piston and cylinder are in real bad shape, so dont fret the engine can still be saved!
and just some words of encouragement, i have brought worse back to life (of that same engine), you can do it!

[rustyapache]

YES! Thanks.
I watched some his bailing wire engine rebuild series direct from the east coast of Arkansas!
Great informative stuff!

I may even go ahead and braze up the crack in the cam cover. One of the arms that run off the cam was brazed either decades ago by dad, or a half century ago by my great grandfather.
