4 Chinese working model hit and miss engines compared.
3 "Microcosm" branded engines $275 to $475, horizontal and vertical, water hopper, fins and radiator cooled. One branded "Enjomor" this model is cheap and way more traditional in construction than the previous Hit And Miss models from China in the past 3-4 years. Available from Stirlingkit.com and Aliexpress for around US$300 to $350.

It's a long vid this week, but then there's 4 model engines. Explanations included for you new guys wanting to figure it all out. Enjoy, and all comments welcome!!

CONGRATULATIONS MR. THOMAS 1K! Keep up the GREAT videos 👍

[@ThomasPCGuruENGINES]

One of my older vids has gone a bit "viral" which has accelerated things a bit. Around this milestone, I've been thinking of you Mr 212 my friend. Your support and encouragement has been appreciated :) ...and all three cats say hi ("mew" actually). Love your vids, keep showing us your older engines as well as epic new ones :)

Hi Thomas, Great upload! I given away my M92 a few days ago. She was still as good as new- but the flyball governor, doesn't regulate it down to a reasonable speed. After lots and lots of plays, I just couldn't get on with it. I have two other Microcosm engines.. Two M90's, and an M94 that I absolutely adore. All my engines, can be slowed down so easily, using weaker springs on the brass weights on the flywheel. From now on, I will only purchase a hit and miss engine, with the above governor system, and I will avoid any flyball governor models like the plague!

[@ThomasPCGuruENGINES]

Hey Gary! Nice to hear from you. That's a bit for others to consider, good advice I think...I have a Microcosm micro hit and miss on the way, M17's hit and miss variant, so it will be tin but yes, have the springs...I don't know about whether it has a ball bearing cam follower which is important or what kind of main bearings...we'll see. I have been kind of avoiding the two new vtwin variants, the harley an bmw, because they would be so difficult to lubricate inside, particularly the camshaft. Hit and miss prototypes remain the best options for an engine you run a lot from China, I agree.

I am a web designer and would love to trade a website for a hit and miss model engine. Would anyone be interested? If not, I understand, no big deal! As a broke student I cannot afford to purchase one myself so I thought about asking if anyone would trade….my apologies if I’ve offended you by hijacking your comment

[@vdel9036]

Very interesting video. Do you plan to couple them on a home made load ? I'd like to see your M12 running, and some tips to help it start and run as well as these you show.😉

[@ThomasPCGuruENGINES]

Key to motors like the M12 is keep revs low, make sure valves hold good compression, clean spark plug often, and TRY to keep that soft camshaft greased. Tughtdn up valve slack as it wears. Move the ignition timing to close to top dead centre for slow running. As for load, I use my finger or a small electric motor as generator. I like hit and miss not under oad because I want long miss. Like I say, the tractors supply my need for the engines under load. Check the vids - they sound great under load :) kzbin.info/www/bejne/pmHIZ56paJiimac

@@ThomasPCGuruENGINES Many thanks for your answer. I print your advice and i'll try to start my M12 on the coming days.👍 My small channel. Mainly my own designed&built air engines, also my solenoid or stirling engines : www.youtube.com/@WalterCoulede

Walter, you are a creative master. LOVE YOUR CHANNEL AND I HAVE SUBBED. Thanks for letting me know!! Love the solenoid engines and lots more I haven't watched yet. heureuse nouvelle année, mon ami

What fuel does your hit and miss engine run best on?

[@ThomasPCGuruENGINES]

I don't find them fussy on fuel. I use standard car fuel petrol 95 octane (no ethanol in it here in NZ yet). I add about 4% 2-stroke small engine oil. Sometimes I run more oil than that, then add more undiluted petrol to the mix to lean out the oil if it's smoking too much, once its getting dialled in. The one piece of advice I have found to be most critical is having ignition at top dead centre. These engines are tiny and flame propagation through that tiny cylinder head space is very quick. Also, we don't want them tuned for power development at 2000rpm or above. They're a demonstration engine giving one powerful kick at the lowest RPM they will reliably keep running at. Timing the spark advanced as they might come from the factory (and original full sized prototype engines were timed for) gives a lack of power at the low speed "hit" that means you'll get a bunch of unwelcome hits until miss speed is reached. So, clean your spark plug before each run, get your valves seated, spark at TDC and valves opening so there isn't resistance due to vacuum. If you have spark and it still won't run, your v\carb might be blocked. See where I'm t with the cute H73 now kzbin.info/www/bejne/gKXGeHemnZ51m7c

I purchased 3 types from 3 sellers on ebay. But they were all sent back. All are shipped from China. On top of that, the items I bought on Ali Express were also returned. It may be impossible to export from China to Japan. I wondered.🥲

[@ThomasPCGuruENGINES]

Konbanwa my friend! You are saying that the post or courier service sent them back and they never even reached you? That must be incredibly frustrating. I guess you tried very hard with a clear address. I am amazed and disappointed for you. These engines are not perfect, but they are fun, Japanese have reputation as fine engineers, check out the near-perfect KyowaGokin KYG 905SE kzbin.info/www/bejne/oV62mIqlhr52rqM

[@user-wl7um5rp4h]

Thank you for your reply. I have already subscribed to that channel. I didn't receive the one I bought at eachine store in Ali Express. Of course they gave me a full refund. I don't know where to buy it so that it can be delivered to Japan.😅

[@user-wl7um5rp4h]

I have purchased a lot of items on ebay and aliexpress. All have the same address. But it doesn't arrive. Strange thing.🤷‍♂️
