That is very small. Well done! You know you are going to have to build a little utility boat to "test" your engine in the wild ! There is always a problem between idle and wide open throttle, usually due to mixture. There is a change in the vacuum provided by the piston between high and low RPM.
Hello, Glad you liked it. Already started the next one. It will be the same cylinder and piston, now that I know how to make them, but a horizontal, water cooled, hit and miss.
Hi Less, I am still subbed to you. I appreciate your' craftsman ship. Nice, job well done. I haven't been doing any machine work for a while. Been making much needed improvements on my house. I rather do machine work, but!
You probably know this but maybe not. It is much harder for a high compression engine to get a spark than a low compression engine. So at a low throttle opening the cylinder isn’t filled with much air and fuel so it’s running at a low compression. When you open the throttle more you fill the cylinder more and are running a much higher compression. It's also harder for the flywheel to keep it running but that doesn't sound like that's your problem. Thanks for the video nice work.
I heard that high compression could prevent the spark, but never had it explained to me the way you did. Thanks for the info and reply. I thought my problem of higher engine revolution was fuel mix ratio, but it may be ignition related.
It’s beautiful. I’ve been trying to make one of these forever. 2 main things I have struggled with you answered. Which was the spark system and if I could use brass for the head. May I ask. What is your piston made from and also what kind of spark plug did you use? Or did you just make one?
Just noticed I did not answer your questions. The piston is aluminum with a vitron o-ring. I purchased the sparkplug from an online vendor: stevehuckss396@gmail.com
Very well done! Thanks for sharing. Amazing as usual! I managed to build my first steam engine, couple of years ago, thanks to your instructions. How can i get the constructive plans for the engine of this video? Ciao
Hello Francesco, I didn't make a complete dimension drawing for the IC engine, like I did for the little steam engines. I just make some drawing, on the fly as I built the IC engine, so that is all I have. It is a .dxf file made on LibreCAD. I would be happy to send it to you if you like. Send me your email to: lesproper@gmail.com
@@LeslieProper Hi Leslie, this is Francesco Alfonso. We got in contact via RUclips, I would really appreciate if you could send me your drawings for IC engine via email (by simply reply to the present email address). Many thanks in advance and congratulations for your works, always precise and very well done. Ciao Francesco
Good morning. You do amazing work. Most impressed with the amount of work you do by hand. I am a fellow model engine builder here. I am interested in your modified ignition system. Where could I find instructions on modifying the grill lighter to work on an engine? Thank you
Hi, I enjoyed your video of your Howell engine. It runs very nice. There are a two videos showing how to make the ignition systems. One is by "mylittlediesel", this is the one I have been using. It is based on one by "Jan Ridder", which is slightly different. They are RUclips videos that will come up if you search on these names.
I should also mention that my latest engine has a replacement part ignition system which I purchased from Stirlingkit. It cost $43.99 US and included a sparkplug. It is describled as a 4.5 volt ignition system replacement part for M90, M91, M17B. I was not able to get my last engine to run and I was confounded as to why it would not run. I decided to purchase this replacement part ignition system and when I installed it on my engine it took right off. My conclusion, which may or may not be correct, is that the reed switches I was using
@@LeslieProper Thank you so much for the information. I have several engines running on hall sensor/buzz coils I purchased from Jerry Howell’s son. That paired with a 6v/12v ATV coil. I haven’t actually had any issues aside from the need for at least a 6v battery. I was thinking I like the small battery option with the lighter ignition. I will look into the RUclips creators you named. Thank you Matt
The overhead valve engine was totally built on the Sherline lathe. I used the Sherline mill to cut the cooling fins in the flat head engine and my old South Bend for parts of the crank case.
@@robopooperscooper The drawings for the IC engines are very crude and basic. I was making them as I built the engines to determine some critical measurements. They are LibreCAD files. I can email the file to you if you want.
@@LeslieProper ohh, maybe because your spark plug doesnt have a resistance or your ignition system had too small a capacitance. it make the spark too short and make for a bad combustion? you could also try to have your carburetor vaporize the fuel more. i dont know, it is still working very good except for the strange problem of cutting out.
@@Francois_Dupont Yes, I have fiddled with carburation, ignition, timing, etc., it seems to run much better with use. Runs better now than in the video.

THANK YOU...for sharing. Fantastic work, the brass is a real added detail, just beautiful.
Great build again les!
What an absolute gem. Thanks for showing it.......... Superb !!
Well done Les, excellent work

Looks amazing
Beautiful. 👌
That is a ripper .
A brass case electric jump starter , thanks for sharing
It really is an interesting and fascinating engine and superbly built Les. I was sure that you'd get it to run - you never give up :-)
Great full ideas
So amazing👍👍👍👍 very very nice...
cool

Great little engine. I can see a spark between spark lead and top of spark plug, should this be there?
It seems to work better with the gap. It also tells me the spark is working.
You probably know this but maybe not. It is much harder for a high compression engine to get a spark than a low compression engine. So at a low throttle opening the cylinder isn’t filled with much air and fuel so it’s running at a low compression.

I don’t have a lathe but I’ll see if I can make it work thanks for the pdf

Wonderful little engine Les! Am I correct in assuming this whole engine could be built on a Sherline mill and lathe?
The overhead valve engine was totally built on the Sherline lathe. I used the Sherline mill to cut the cooling fins in the flat head engine and my old South Bend for parts of the crank case.
@@LeslieProper Thanks, that will be a project once I finish a few more of your steam engines. Do you have any drawings you would be willing to share?

@@LeslieProper Thanks Les, I’ve sent you an email with my email address.
Harry
why are you having the wire spark on top of the sparkplug?
The resistance of the air gap seems to make the ignition work better....or maybe it is just my imagination.
@@LeslieProper ohh, maybe because your spark plug doesnt have a resistance or your ignition system had too small a capacitance. it make the spark too short and make for a bad combustion?
you could also try to have your carburetor vaporize the fuel more.
i dont know, it is still working very good except for the strange problem of cutting out.
@@Francois_Dupont Yes, I have fiddled with carburation, ignition, timing, etc., it seems to run much better with use. Runs better now than in the video.
Do u still have the pdf plans for one cylinder single acting steam engine
Yes, send your email to me: lesproper@gmail.com and I will email it to you.
I’m not sure iff it worked or not I almost never use email lol.
