Could be made of solid gold with platinum trim and would likely still be declaimed as junk by this crowd.

Paul, going to Delaware Valley show next weekend? I will be there on Sunday, if it isn't raining. That does look like a neat engine. Says it can run on kerosene - hit & miss? I wonder what they use for lubrication? I don't see any oilers!

I looked at the engine you posted and thought to myself that it looked very familiar. For as many times I’ve been hit in the head and inhaled gas fumes I actually recalled where I originally saw it. Enjoy the link, apparently some company over seas did.....:uhoh:

P.s the chinese engine on the website is missing the push rod. Buyer beware.Lol!:crazy:

The plans for the bar stock engine were available from a free download.... I have a set that I printed a couple of years ago... Really wanted to build one ... But for $220.00.... why would you go through the Hassel of the build...
Maybe I can talk my girlfriend into buying me one for Christmas.... :D. Wish me luck... I'll need it.. :wave:

Yeah, I wanted to build one too. I have a the machine tools to to it, but currently no time to pull it off. Really, for money it’s a good deal. You could pop your girlfriend the question and that may bribe her to buy it for you! :uhoh:

I also bought one of these Chinese knockoffs of the Kerzel design model engine. I thought it was missing the pushrod too but I found it loose in the box. It is 5.5cm in length and has a rounded tip on one end.

I’m actually impressed by its construction. It is a very good looking CNC machined assembly constructed mostly of anodized aluminum. It has a steel cylinder liner, roller crankshaft bearings (a bit rough), and what I think are heavy stainless steel rims on the flywheels.

I run mine on Coleman fuel with some 2 cycle oil mixed in. I can adjust the height of the fuel tank mounted in a hole in the base to get the optimal fuel pressure. I added a check valve to reduce double sucking with mixed results. I also added a cylinder oiler and crank throw grease cup. I haven’t hooked up the little generator in the pic yet.

For such a small model it (eventually) runs pretty good. It came with a nice small ignition module but it stopped working after a couple of hours operation. Banggood would not send me a replacement so I had to build my own.

Its a great price for a fully machined and assembled model h&m engine. I could have built the Kerzel design with the very good instructions he has made available. And there are other model engines that I lust after, like a 1/4 scale Rider Ericsson. I have the equipment and basic skills but lack the patience required to see a model project all the way through to completion. So I wonder why someone can’t send off a bunch of casting kits to China and have them machine up all the parts real cheap. This little engine shows they now have the expertise and quality control to do a decent job. Maybe its only a matter of time before we see some larger models from China.

Hi all, first post. So glad I found this forum! New to H&M but have always loved these engines. I live in Indiana and have been going to the big show in Portland for several years. Planning to get a full size engine this spring or maybe next fall.

So I too ordered the Chinese H&M. It’s very hard to start. I’ve watched the YouTube vids and those start with a couple of flips of the flywheel. It’s run about 5 times for maybe a minute each time. I’ve even tried either and it doesn’t seem to help. It’s got a healthy spark and I’ve got the bottom of the fuel tank about even with the carb. The needle valve is adjusted close enough for it to run once I get it started. Any suggestions or tips? I’m afraid I’m on the verge of getting some sort of “flywheel flipper elbow”. ;)
Thanks, Gunther

One of my friends has one of these engines. It is a great little runner and starts easily.
He told me he wants to take it to a rally. He has a big covered in trailer. Just for a laugh he will back up to his site drop down the ramp and unload it with the winch. he should get a few comments.

Update for anyone else that might happen across this subject looking for hints and tips for getting their Chinese Hit and Miss engine going.
Mine starts and runs good now. I was flooding it badly, fowling the spark plug. I did two things. I moved the gas tank down so the bottom of the tank is about 2” below the carb inlet and after reading Kerzels plans and info I switched from Coleman fuel with 2 cycle oil to Coleman fuel mixed with WD40. The WD40 provides some piston lube but seems to keep the plug much cleaner. Now I prime it by putting a finger over the carb and giving it a good flip. Usually starts with just a flip or too after that.

I also ordered one of the Chinese engines on banggood but I don't understand how the ignition is supposed to work and if it fails since there is no points and how would you diagnose it if there is no points.

I finally ordered one of these little engines too. Placed the order on 7/24 and it arrived today - 8/01. Pretty quick, I'd say.
Fuel tank got a little beat up in transit, but nothing went all the way through, so I don't think it will leak. :shrug:
Has anybody had to adjust the ignition timing? Mine looks like the magnet passes the pick-up at or slightly after TDC. Or, is that an acceptable setting?
What voltage is the ignition supposed to operate on? One of the reviews on BangGood site says he is using a 18650 3.7V rechargeable battery. Other reviews cite regular failures of the trigger module due to voltage spikes. Let me know what you all have found. There was no documentation or instruction manual provided. Probably wouldn't be much help even if there was...
Need to get started on a nice base for it now.

Mine uses 3 double a batteries and that extra wire that comes with the engine you ground the engine to the negative of the battery. A friend told me if you go to a dollar store they sell flashlights that hold 3 double a batteries. Take out the battery holder and solder wires on the holder for plus and minus.

Boris (Post #11):
Where did you get the miniature oiler and grease cup that you added to your model?
I would love to include those on mine.
