Hi Thomas, lovely recap of your beautiful engines, hope you have another great year with some more fab engines to show us! I have a new M17 but seems like the hall sensor is faulty, and a lovely Musa Hoglet V twin to get up and running soon - Best Regards and Happy New year to you. Ade
@@ThomasPCGuruENGINES I do indeed, I ran the hoglet last night, started straight out the box and its a ripper! The Retrol engines seem to always need a bit of work to get them to run as you want them to.
Bonjour Thomas, As great collector and skill mechanic, how many of your engines start out of the box without any enhancement ? Which one would be your preference ? And when comes the vertical Retrol Hit & Miss engine ? Bonnes fêtes, Amicalement, Raphaël
Nice to hear from you Raphaël. For me, the pleasure is getting the engine running what I can achieve "perfect" and learn a bit. Early engines like the M90 needed valve lapping, new main bearings, retiming the exhaust valve. Lately, engines like the Microcosm OKMO v twins need nothing done. Having to lap valves seems to be a thing of the past. I still find that a batch of engines built by an engineer's employees rather than the engineer himself will not be assembled so well. OKMO's tiniest Stirling engines are perfect out of the box. But their Rider Ericsson's usually need fiddly pump work and are simply too small. Hit & misses can always use cam and detent latch optimisation. Kontax low temperature engines are perfection, but their high temperature mini engines have machining tolerance issues with the pistons-cylinder fit, which I guess is acceptable. I don't know when the Retrol MUSA vertical will arrive, surely soon???
bought a retrol hm-01 and it arrived for christmas (i didnt buy the base since it wasnt in my budget, and i could make one myself). Call me an idiot because i spent hours trying to get it to have compression but then i realised the spark plug was still in the box.
Bwaaaaaaaaaa hahahah you made my evening. My dude, we have all been there ....Also, for this quality engine, give credit to the perfectionist, passionate engineer at MUSA. "Retrol" is just a retail brand partnership of convenience :) You have an heirloom model right there
Best wishes for your bloody gorgeous holiday season and a great New Year:)

Thanks Ade, it's appreciated :) Same to you
I have been curious about the MUSA hoglet as I bet it is MUSA's superb engineering. Do you feel that?

@@AdeSwash Thanks Ade. MUSA engines for the win
that m19 engine looks like it had a lot of mods done on it
Mainly I like to add a switch so that it only fires during the hit part of the hit & miss cycle so it's not wasting battery and it's quiet
@@ThomasPCGuruENGINES ah
that explains it
