Sorry for the camera shake in the last one. It really screams so loud that iphone is struggling to keep up 😅
Engine behaves nicely, just connect the fuel line and flip it until it starts. Needle needs to be around 1,5 turn open otherwise will flood easily. Immediately when the engine start just open the needle to around 2,5 turns open and it will run nicely rich and undercompressed like in the first clip.
Lean out the needle a little and it will run fast undercompressed.
Increase compression and open needle to around 2,25-2,5 to find the peak setting.
Sugden is very loud aswell. You can run it without earprotection but you will know afterwards that it wasnt really good for your ears 😅
Engine weights 112g so it is very light for its size and power. It has now done 37 runs. Propably too light for years of service (or definately) but sure is a fun machine. And the casting by Vincent Chai is absolutely flawless would there be more I would make a second one immediately!
