MUSA F1-2.7cc Mini OHV Vertical Single-Cylinder Four-Stroke Air Cooled Gasoline Engine Internal Combustion Engine Model Crafts
Our Story: In recent years, EngineDIY have cooperated with MUSA to launch two single-cylinder engines, "Whippet" and "Red Dog" that pay tribute to the classics, which have impressed many model engine enthusiasts. In September 2023, let us once again pay tribute to the great craftsman-George Luhrs. George Luhrs spent most of his life making engine models of various sizes. Unfortunately, he passed away in 2014. In order to commemorate this great craftsman and continue his spirit, this time we bring the George Luhrs Engine The work is a prototype, a remanufactured mini single-cylinder four-stroke engine. All parts of this engine are precision machined by CNC, and the crankshaft is hardened and equipped with bearing bushes. The engine design adopts an overhead valve structure, forced air cooling with a centrifugal fan, an external mechanical ignition system, an adjustable ignition advance angle, and a visible and transparent small fuel tank.
Features:
.A Tribute to the Classic: The Luhrs miniature single-cylinder engine will evoke retro nostalgia and resonance among more engine model enthusiasts and players, and attract widespread attention and discussion.
.Exquisite Appearance: This miniature vertical single-cylinder four-stroke engine has a unique and beautiful appearance, with an overall silver color scheme and a compact mini structure. You will definitely like its working conditions.
.Ingenious Design: The engine adopts an overhead valve structure. The cam housing on the right is a fan cover with a mini cooling fan inside, an external mechanical ignition trigger, and an adjustable ignition advance angle.
.Excellent Quality: Fully CNC machined, hardened crankshaft, equipped with bearings. The surface is sandblasted and anodized to show the mechanical texture and beauty of the engine.
.Excellent Collection: This mini single-cylinder gasoline engine model is not only a highly collectible and visually appealing engine but also a perfect addition to any model exhibition. It also makes an excellent personalized gift for mechanical enthusiasts.
.Warm Tips: Please note that the engine comes pre-assembled and tested and does include a spark plug, CDI igniter, and fuel tank. The base is not included, please bring your own or purchase it separately. Please use the machine according to the instruction manual to avoid damage to the machine due to improper operation. If you have any questions, please contact us in time.

Here first pictures of the F1, test run has taken place,
the engine runs satisfactorily.
The cooling is not in order because the fan blades run upside down. On the other hand, Musa has not managed to seal the engine properly!
I demand from Musa to deliver a new fan wheel with the blades run the right way!
It helps no one everywhere to carve his "Musa" but the engine with defects to throw on the market.
A brand is measured by the perfect execution, not by the marking on the parts.
Video I post when Musa has delivered and the engine cools properly.

First Impressions of the MUSA F-1 engine
Received the MUSA F-1 yesterday and was surprised at how nice it was when I unpacked it. So today I gave it a go to run it. So right off the bat the white points wire was broken free from the connector so had to re-solder it back on. So after doing that I put in some Lighter fluid and hooked up a battery and started to crank it over, seemed like it had allot of compression at first but after several attempts it seamed to loosen way up and engine oil and fuel overtook the cylinder. So popped off the head and drained the excess out. Back at trying to Start it and it just wouldn’t go and so tried adjusting the mixture and also the timing. Still nothing so I then drained the lighter fluid and use 50-1 fuel mix. Proceeded to crank it some more and it finally took off. I will try straight gas next time. The one thing I will say it the base should have been designed fully to hold the batteries and electronics. Also it really dumps excess oil out the points end of the crankshaft. Overall I’m very very pleased.

Musa F1?
Here is a first summary of Musa F1 engine.
As expected, the engine is made of very well-fitting CNC parts and looks very good at first glance.
What bothers me is that Musa has thought the engine to the end but has not realized.
Why do I design a base that is intended to hold an AA battery and has space for a CDI ignition if you then do not install it?
The engine runs counterclockwise but the fan wheel is designed the wrong way round, the blades are the wrong way round, what's the point?
Maybe Musa can comment on this.
I'll post more when the engine is fully tested, then again with video.
Many greetings Harold
