Post by: creepy on June 20, 2019, 06:20:36 pm: Great little engine Jan.
I love anything that involves miniture engineering and this engine certainly looks well made and goes fantastic.
BTW, I also purchase stuff of Jin and find him very good to deal with.
Please post up more videos.

You definitely need one of those Zippo fueling station.

Post by: Nick on June 12, 2019, 09:51:42 pm: Very neat fuel station! Off to check the prices they bring now...

EDIT: OUCH about $300 :o

Yes, i know of those Lenn...

Unfortunately they tend to sell for more than these engines, so found that adding one just to fuel this one was a bit of an overkill.
That said, should you (or anyone else) find one locally, set up for sale at a more reasonable price, i would definitely be interested.

Post by: Swift Fox on May 06, 2019, 11:47:15 am: Good to see you stocked up on fuel Jan, how long does a tankful tend to last?

Only the small 125ml cans of Zippo fuel are available in the UK, i've never seen any of the big ones for sale over here.

Would be interesting to see if you could convert one of these engines to run off a butane/propane source.

Post by: St Paul Steam on May 05, 2019, 09:03:52 am: I'm not to worried about the oil mixture, I just now started putting a few drops of marvel in the Zippo can.

Post by: classixs on May 05, 2019, 07:55:31 am: Well, probably kicking myself by sharing this Roger, as there´s so many wrongs in it from en engineering point of view, but i´ve only been running it on pure Zippo fluid until now.

First off, to properly hone it/run it in, i wanted it running as abrasive as possible, to see if i could spot a difference, once it had a bit of time on the clock.
Until now the running characteristics has only been improving, and seing how it throws greasy stuff from the exhaust already, i´ve chosen to stay with pure Zippo fluid.
I might regret this decision some day, if i have to take it down for a rebuild due to my choice, but fortunately i know who to blame then.

Post by: IndianaRog on May 05, 2019, 07:41:48 am: Jan, I can see a Zippo shortage developing in Denmark shortly!!!

Great fun!

Just curious what Zippo/oil ratio you are using? Everyone seems to have a favorite and they are all over the board. I WAS using 5:1 Zippo to Marvel Mystery Oil. Just cut back oil content, as it seemed a lot of oil was accumulating around the open piston end of cylinder. Seems to run fine on 10:1 ratio of Zippo/Marvel Mystery Oil with less oil buildup which I assume is better for spark plug too.

Wish there was a bit of science behind these various mixtures !!!!

Post by: Jim on April 29, 2019, 10:09:12 pm: You gotta' be happy with that Jan, what a beauty!
Title: Re: Microcosm M90 Hit & Miss Engine Arrived
Post by: jkbixby on April 29, 2019, 01:36:55 pm: Pretty flowers and pretty engine - glad you got yours quickly Jan!
Title: Re: Microcosm M90 Hit & Miss Engine Arrived
Post by: Hero on April 29, 2019, 11:59:13 am: Nice engine, Jan. Nice daisies, too.

I've been contemplating buying one of these, but I'm suddenly in the midst of negotiations for another model, so it may have to wait.

Post by: IndianaRog on April 29, 2019, 11:25:07 am: Jan, happy for you and like Bruce, love the flowered backdrop!

Post by: Steamandoil (Tim) on April 29, 2019, 09:46:09 am: Really glad a few of the long ordered hit miss engines are getting into the proper hands. Probably going to be some interesting adaptations over the next few months.

Post by: classixs on April 29, 2019, 08:28:05 am: Since i took the leap, and clicked a BIN on April 11th., i have so been looking forward to the arrival of this one...

Happy to report yet another great succes, when dealing with Jin.
Fast shipment, bulletproof packaging, and a fantastic product !
(Shipping took just about 1½ week, if deducting the days spent, being kidnapped for ransom by the customs service, and my own workrelated absence from home)

Short movie from one of the several "test runs" allready performed here...can´t really get that grin of my face right now:
