Step 8.
Now clean off al aluminum dust befor you remove the protection from the crankcase. Compressed air and brake pads cleaner works fine. And the engine is ready for new prop hub, electronic ignition and muffler.

Bare engine weights 23.9 oz. Original carburetor weights 6.5 oz. Prop hub about 1.5 oz. So the engine can be less than 32 oz plus muffler, radial mount, and ignition module. This is the weight of 'brand name' airplane engine of that size.

I'm going to use gasoline with glow plug on my engine. So entire ready to fly weight will be:
Engine (with prop hub, carburetor) = 31.9 oz
Muffler = 4 oz
Radial mount = 2 oz
On board glow battery = 2 oz
---
Total = 40 oz. I think it is not bad at all for the power, performance and fuel economy.
