Hi
Is Coleman fuel also good for bigger engine like the Star engine ?
-
you taken that engine to a whole new level Alan , great job.
-
Some excellent enhancements Alan.
Thanks for posting the video.
-
Continue to be enthralled with these little beasties .... and gathering all the tidbits of info being offered!
-
Some very nice upgrades you´ve added there Alan, well done !

Hi
Here my engine from Eachine with new bronze bearings, oil cups, better carburator control, on-off led lamp and wooden base.
All made by a model engineer friend from Geneva.

I did a fuel test on mine today & filmed it but am having computer problems and can't upload it, I couldn't get the engine to run on white gas (coleman style)...but ran great on lighter fluid (Zippo type) and it hardly stunk. I ran the engine for over an hour (3 tanks of fuel) & Ang didn't even smell it...the engine runs very cool also, my thermo electronic temperature pointer never registered over 116 degrees .
got the computer working, here's a vid

It's great Gil is up on this stuff. That's a pretty good explanation of the fueling logic. The Coleman fuel is pretty easy to find and cheap enough for this use.
I think any small amount of Marvels oil or 2 stroke mix would be fine. A drop or four in the small fuel tank is certainly better than none.
In the end, we will probably come up with some pretty exotic attempts to refine and improve running and lube. MORE POWER!!! lol.

Jim, Bruce, et al, These should be run on Coleman Fuel which is Naphtha.
It is also called White Gas. It does not smell bad like automotive gasoline.
Car gasoline has lots of nasty poisonous additives in it that are designed to be pushed through a catalytic converter at 1800 degrees to react properly. Car gas also has ethanol and between that and the other additives it will begin to eat into your engine parts. In a cool running engine like this these, the additives are just real stinky poison. If you don't have Coleman fuel handy, Ronson or Zippo lighter fluid is also a naphtha product which will burn nicely in these little engines.
A few days ago I ordered 2 of the Eachine ST1 from Banggood. I hope they ship them. They never were able to ship me the blue ones I ordered last year.
The engines are the design of David Kerzel in Florida. He spent a couple of years perfecting the design and then published the plans for free use by the public for hobby machinists to build for themselves. The co-operative where Jin's stuff is made builds these to David Kerzel's plans and they have done a nice job of it.
The newer natural finished versions are a substantial improvement over the original electric blue anodized pieces. I payed Jin 380 USD for my older blue one and $235 each including postage for the two I just ordered. It is my understanding that another site called AliExpress also sells for a little less. I know nothing about how reliable they may be. So far I have not had luck buying gas engines from Banggood but they have always refunded quickly when asked. I have bought a number of Jin's Microcosm products like small steam engines and governors for about half the price I paid Jin for them.
The main thing is if you get one, please use Coleman Fuel or similar.
I also mix a little Marvel mystery oil with the Coleman Fuel (or 2 cycle oil).
They don't run hot enough to burn the oil. They just push it out through the exhaust while they run.
Gil
Thanks for the heads up Gil - will use Coleman fuel in my AliExpress engine if and when it arrives. And how much is "a little" Marvel Mystery Oil - any idea on the gas/oil ratio?
-
I have come to understand many run these on Coleman white gas, with a dash of wd40 or some other oil mixed in. Some say 2 stroke.
I think I might have to pony up on one of these. Just so dang neat. And fun. And noisy.
Make it where I can do a wheelie, I'll be a happy man!

Bruce do you get much petrol smell and exhaust smell from running these?

I would think that Coleman fuel (white gas) would likely be the best bet, as it is essentially "pure" gasoline without any additives, and specifically intended for burning in places where people and foodstuffs would be exposed, thus producing a minimum of exhaust fume odors.
I'm very open to alternative fuels as well, Coleman fuel sounds real good and I will give it a try this weekend , I think WD40 might be a tad expensive.

yes definitely,(exhaust smell) especially if you run it to rich, I ran it in the house for about 30 seconds to show Ang I got it working good...then back outside it went, even in my closed shop 15-20 minutes was enough to make a noticeable stink with some eye irritation. i was asked some questions about it from a you-tube viewer & this was my reply...... "it really only has one speed ,you can lean out the carb or make it more rich & change the speed somewhat, I am still learning how to operate it but I found about 1/2 turn counter clockwise from completely closed helps it to start (a rich position) then when it warms up you can adjust the carb knob back to not quite a1/4 turn, it also helps to squeeze the fuel line right under the carb (before starting) seems to act like a primer bulb & definateley helps cold starts. there is no on/off label for the switch, but mine is (looking from the back) switch to the right is on".
i'm going to experiment on different types of gasoline & see what it prefers. i'll get back on here when I know anymore. i also intend on making a miniature roll around cart for it.
Bruce, do you have to run it on gasoline, or would something like Zippo lighter fluid be adequate and maybe smell less??? I'm going to need some guidance on fuels as I see various mixes talked about including addition of WD-40, Coleman camp fuel etc.

That runs really well Bruce, i can see why they are popular. I've often looked at the Red Wing models and those Maier gas engines, seems you got a good deal with that engine.

Thanks very much for that detailed reply Bruce, much appreciated mate.

Thank you Bruce, you've answered a lot of my questions within your videos. I am very interested in one, but I think the prices of these may be on the rise for awhile... still a low price compared to the alternatives...

I watched these movies, as soon as i got the notification from your channel on my phone, and once again when i arrived back home from work, just to get all the details on the big screen.
Amazing looking and very nicely running engine this, with just one downside as i see it.... Now i want one of these as well (https://emoji.tapatalk-cdn.com/emoji28.png)
Great show Bruce, thanks for sharing !
Me too Jan :)

Lol...Jan,Larry ,I need to Branch out into another hobby like I need an empty wallet, these are a lot of fun and a little bit smelly, I'm going to make some kind of two prong attachment for my drill to start it because they are a little hard starting initially, once warmed up they will fire right up with a flick of the wrist.
I will update this post as I get more running time on it.

Hi
Nice engine for a good price.
I have also ordered one.
Is not from Eachine (they are making rc drones) and sold by Bangood ?

Alan ,I'm sure yours is probably made from the same company and probably a co-op as well oh, that is a very good price.
