Here is a "50" :plemplem: compared to a "45/140" ...

Besides the size difference, are they compatible ? Can you mount the "50" on a SI 20/20D ?? What would be the equivalent in air ?

Nobody knows ?? (

I think you have to try. If nobody had try this before than nobody can tells you. In an other topc the academics argue only about in which way the size of a jet change the work of ya engine. so try and let us know.

BRO

I can tell you that the one with no hole is for a SI 20/17 and the other one is typical from a SI 20/20D.

I was given the "50" for a SI 20/20D, but I think it is a mistake. And running with is *way* too rich at Low RPM !!

That's why I was asking...
