Posa Carburetor Tuning

Rare historic footage of Rex Taylor, founder of HAPI Engines, a famous experimental aircraft company.
I found a VHS tape with this awesome content, so I decided to convert and let the world get a little more knowledge about this very hard to find information.
This video will also help you understand Posa, Lake, Star, Wahl and Gardner carburettors.

Just like a electron square slide. Totally changed the performance on my xr650

I hope they make these in 19mm or maybe 21mm I wanna try to run one on my two stroke 74cc airsal. Right now the smallest one I can find is 26mm. Love these vintage videos hope this very interesting and intelligent man is still with us today
