Hi Group
Here's a link to video that allows 3D view of carburetor working:
https://www.youtube.com/watch?v=toVfvRhWbj8
Next iteration video to be more Rotax specific can incorporate Constant Depression feature showing how some leaning at altitude works and why it's critical to vent float bowl to airbox when turbo charged and how selecting impact air going to float bowl richens mixture. Also how enriching circuit operates compared to traditional choke, how the darn mini enrichment jet in floatbowl so easily can clog and how bad it is to overtorque float bowl and warp it where it can restrict main jet and cause leaking between float bowl and carb body causing a leak that causes lean mixture for turbo charged engines.
Could also be nice to see a 3D working model of Fuel Pressure regulator of 914 showing how restricting flow back to fuel tank causes over pressure as does running 2 parallel pumps in parallel.
Oh well, for now enjoy Carb 101.
