New lamp

Very nice looking and it runs even better then it looks, made a display stand/lamp so it can be enjoyed when not running.
Not really impressed with the customer service. Took about 5 weeks, and many emails to get a replacment part for the part that arrived broken.
The engine is very impressive now that it runs however.

Excellent Hit and Miss Engine

This engine not only looks good but it runs amazing as well. The wooden base really looks great with the engine and is worth the few extra dollars to get it. The engine fired up right out of the box without any issues. I like the fact that it has a two speed lever. It come with a lubrication glass tank and two lubrication points on the shaft. Don’t think about it just buy it, you won’t regret it.

Finish is very well done
Great base to mount it on and a box to hide electronics
The black exhaust stack gives it the ++ in looks
2 speed lever is excellent for slowing it down
Nice brass fuel tank
It runs very smooth, overall I give it a 9.9

Thoughts on the engine

First impression out of the box is it is BEAUTIFUL. The finish is outstanding. Ran first go straight out of the box. I like to tinker so it was a lot of fun changing spring pressure and fiddling with adjustments. If you want a display piece that looks great and sounds good or something to challenge you in your tinkering skills I personally wouldn’t pass this one up. It’s one of my favorites hands down in my gas and steam engine collection.
