shouldn't we measure the energy contained in the fuel, and the power generated to get the efficiency, but I like the other work shown here.

YEA closed it up for lubrication....lol....did it to make sure people be more likely to bring it to shop.early example dealers making sure you bring things to shop.john deere bought waterloo mfg and foundry in 1925 they cast engines for 66 companies...well 1926 the other 65 engine companies were out of business unless they could cast their own parts what john deere did not get international IHC got the rest

Great sound.

Thanks so much for posting this! I really enjoyed your explanation and presentation. I have searched for this info for a while and your video came up out of the blue. Warmest regards!

I really enjoyed your video. I realize it’s been a while since you put it out. I hope you are doing well and want to thank you for contributing to something I’ve been interested in!

Is that a treadmill motor you are using for a generator?

Belt dressing works good.

Love hearing this under load.. when I was a kid.. they always brought these to summer festivals and fairs as Ice-cream freezer engines.. so you could tell when the ice cream was getting ready to be done as the engine would hit more and more.. and then the crowds would start to gather because they knew the ice cream was almost ready! old engines were big here in the Ohio area.. lots of farmland.. lots of people whp worked for railroads and the automotive industry back in the day.. and so there was many people who knew mechanical machines.. I love listening to David have fun with this machine.. just like many of the men I met as a kid who built these things.. i was always so fascinated

Very professionally demonstrated ! The beer Babe is really easy on the eyes !!

Hay that was very interesting, I have never observed a hit and miss engine under load like that before and I was surprised to learn how much heat was generated on the cooling system, so you really can not run it at full load for very long. You for your video I learned a lot

Thank you for making this video. My motorcycle has a belt final drive, although it’s toothed so I guess not as efficient as a flat belt. Am I correct? By the way, consider me subscribed.

Wish you could do another video as to how to keep the pulley on under a load

Hotness? That must be an imperial measurement. Excellent video Dr Cave, I never gave much thought to the output being AC, but there’s no commutator so AC it must be I haven’t seen a magneto in more years than I care to recall, It was an impulse maggie on a Fordson Major and I was about 5 Years old, my father warned me not to have my hand anywhere near the output spouts when I cranked that puppy. I would love to know how they change from impulse to direct drive, I’m guessing via fly weights, they were certainly capable of throwing a good fat spark in impulse mode.

This is great!!!!!!!......I don't know anything about these engines apart from I like them !!!.... How's the fuel consumption..???

Very good explanation and very well done!

A fine and most interesting presentation! Thank you very much!

excellent i learned a lot thank you

Oh boy it had a pretty bad miss probably only running on one cylinder, might want to check the distributor cap. At 700 watts I wonder how many gallons an hour it would get. Love the video Thank you!

You can compensate for that strong AGC by using a compressor on the audio in post-production. Depending on the software, it may be able to completely eliminate the gain fluctuations.

GREAT JOB 👍 Answered a lot of my hit and miss questions. I know now that I must have one of these. Thank you for the video.

Sounds like Joe Pera, calming voice

never misses tho does it

Wow, that's a well-running engine.

nice

Could use a new coat of paint but I like it. As far as the value of an antique like this, would it depreciate the value by painting it?

Cool to see one of these type of engines run loaded. At events you always see one of these running unloaded and running super slow. Nice to see how one of these would've sounded in actual use.

Old stuff was built to do WORK for a long ass time, with proper maintenance. And when it finally broke, it was easy to fix. The way it SHOULD be. You didn't just go to a store to buy some shit and throw it away when it broke.

Thank you for this. I like to hear these under load. I recall hearing hit miss engines running oil jacks as a kid. My father explained these engines to me and what they did. The cadence on them was interesting. As they pumped up it was working hard, like this one on the lower stroke they didn’t hit.

What kind of generator is that? How does it regulate voltage?

What size pulley is on the engine?

As a physicist PhD I need to say: Great contribution; hopefully many people will learn a bit from it !

**I've watched quite a few videos on hit & miss engines, but this one was BY FAR the most educational and interesting. None of the dozens of hit & miss videos I've watched, have 'bothered' to delve into the actual performance aspects in any meaningful way. With most of these videos, it's just "hey, look at this old engine. It runs"! But obviously there more important reasons for why these engines were produced, aside from just "look at it run"!** Yep, it turns out that people didn't just buy these things as "pre-television entertainment machines"!😂 It would be interesting to know how much torque this, and many other, larger hit & miss engines made. Back in the early 20th century, horsepower didn't seem to be the most relevant, end-all measurement to determining how 'powerful' an engine or a vehicle actually was! Those WW2 era 2.5 ton, 10-wheeled military cargo trucks("Deuce and a halfs"), only produced something like 91 horsepower, but could pull its own bulky weight, AND 2.5+tons of cargo, and 2-3 passengers up through steep, narrow dirt roads in the mountains of Burma! Once you mention that to the average Joe, he will usually have trouble believing that feat to be possible with just 91 hp!

“In 1922 John Deere revolutionized the industry by copying IHC in enclosing their crank cases” I think is what you meant! Just kidding of course, these E engines are popular, and an Amish family uses one to make ice cream at a show near me. Great video!

Very nice video. I have seen all types of hit or miss engines but that John Deere was something else. Very interesting data.

The load test begins at 9:00 minutes, nice to hear a H&M engine firing nearly every stroke :-)

Nice work and very interesting. Thanks for sharing

such good job on video and dont pay no mind if see any negtive comments

Good Work !! We want to see the pretty gal in the boots !!! This was a very inspirational video and I plan to search out an engine of my own! Thanks Mr. Cave.

video starts at 5:04

Fantastic video. I've never seen a hit and miss do much more than run an ice cream maker. Great to hear it getting a little workout. Very informative video. By the way, do I spy an LGB box on the shelf?

Suppose you could direct couple the generator to the crank pulley centerline, so its free to rotate, supported at the ends, then have a 1 foot rod bearing down on a scale then increase the load until the rpm's drop, that'd give you a direct brake torque number.

She didn’t have much compression new!

Fabulous video and wonderful mathematics.

I too like the loaded sound of a V16 EMD 567 at notch 8 at 7 mph.

Finally someone displays one of these early engine under load. Thank you

Very good demonstration! Thanks for making this video for us. I hope some day to get a nice flywheel engine to restore. Love to hear these engines at load. It's amazing and (but not unexpected!) that she still puts out about rated HP after 100 years, as well!

why not a superintend belt

I want to be your neighbor.

Excellent demonstration and overall performance analysis. Thank you for sharing.

You got to tell me about the pulley on the JD. I've never see one that large. Is that a home made unit or some you found?
