Yesterday, I got a notification that my engine has been shipped, so I guess it’ll be almost another month yet, but we’ll see what happens. :)

Mike, I got my 2nd "new and improved" one today. From the time they actually shipped it until it was on my porch was only 4 days. Good shipping service there.
I still haven't run either one, but improved one does look "improved". Good luck.

I gave up on the Eachine and other cheap options and finally ordered direct from Jin at Microcosm for $330 delivered. As usual, great and fast service.

Now ya tell me.....
I got yanked around quite a bit from the Eachine seller on ebay, claiming it was shipped, sending me bogus tracking numbers (which were the same numbers another friend got) and finally being told US customs wouldn't let my engine through and was given the refund that went to Jin instead. All to try and save $30...

I just got mine this week. I had ordered it in late March. The exhaust valve was being held slightly open by the pushrod so I was getting no compression. The flywheel with the weights attached was also assembled to close to the engine frame. This causes the catch lever to never hold the exhaust open. Fortunately I noticed this before I tried to start it. Both easy fixes and it fired right up. Also seems to be a little hard starting for me however. I'm trying to come up with a nice solution for the spark plug wire as mine came with no boot, connector or anything other than the wire. Definitely needs a cylinder oiler however. I could feel the O ring getting tight after a bit of running. I think zippo fuel helps to lubricate the cylinder.

Slip a piece of clear fuel line over the spark plug wire and then to the plug. That's all mine had on it. Works good. I oil mine with a drop or two to everything before start up. You can even get to the cylinder with piston at tdc with a long spout oiler. When starting cold, hold finger over carb for a couple of revolutions. Then use finger as choke plate till warm up.

Do you recall if you found a set screw to slide the flywheel out? I think mine has the same issue, but i have not located a flywheel set screw. Thank you

Hi Team,
the flywheel retaining set screw is in the center of the flywheel hub, in between two spokes, way down in a drilling on mine--a standard long/short leg Allen key of suitable size is all that is needed to access it.
Hope this helps.
Cheers,
Eddie B.

Yes, mine has two set screws in each flywheel hub, one side came loose after the first 15 minutes of running

anyone have any idea on the size of the orings for the piston?
I have tried several kits so far with no luck on finding the correct size.
Thank you

I finally got mine today after 3 months of waiting, 6 months if you count my first order that was cancelled. Everything seems ok, but the crankshaft is a little loose in the needle bearings. Anyone else notice this?
Yes, everyone that I know with one has said the same, including my own...

Anyone else notice this? Mine seems a little loose also but does not seem to affect running. I think its made this way as a clearance type thing. I always use a drop of oil on bearing as well as on other parts before starting

I’ve been following this thread all along since I started it, and seeing the upgraded version, I just had to order the Eachine ET1 STEM Upgrade Hit & Miss Gas engine. I ordered it 5/29/2019 at 7:42am with standard $2.99 shipping and $4.60 insurance instead of the $18 +/- priority shipping. I got all the notifications, order received, order #, order processing and order arrival date 6-11-2019. I said to myself ***SURE***, and was ready for the “WAIT” and see…:uhoh: . This afternoon (5/31/2019) I heard a truck out front :confused: and didn’t pay any attention to it, as I’m not expecting anything, and the doorbell didn’t ring. The Wife came in around 4:00pm and said this package came for you? WHAT!!! I checked out the black plastic bag that had a small tag on it as being a Sterling Engine made in China. In the bag was a 10” cube, unmarked box. Of course, I opened the box upside down, but that wasn’t a problem as I unpacked my “NEW” well packed Eachine ET1 STEM Upgrade Hit & Miss Gas engine :yikes: . I still can’t believe it only took 3 days to get to me . “What a surprise” as it came out of a warehouse in South Brunswick, NJ. I guess Banggood is getting their act together. It sure is a nicely built and looking engine that I’ll someday fuss with. For now, it will just be a shelf pet collecting some KUDZU “DUST”. Just having “FUN”, even in NJ :confused: on the way through :p .

Got mine mounted up to a 3D printed base. Turned out pretty well. Ran it for about 20 minutes or so and then the ignition died on me. Looks like I'll be building my own ignition for it unless banggood sends me a new one.

Let us know what you end up doing for an ignition. I seen replacement ignitions for the original blue model but not for the updated model

You can get a complete ignition package on ebay from Jin. It has everything.... the module, spark plug, battery holder, switch, and hall sensor pick-up and includes all wiring.
He gets something like 55 bucks for it but it has everything.

It shouldn't fail in as little as 3 weeks. I wonder if a ground came loose?
