Hi Guys,

Maybe you will be interested to see this experimental video changing different types of Poppet Valves and settings and recording the idle and high revs RPM. Surprising early and late G4 carburetor body significant difference in the venturi.

Cheers,

Hello thecarbymaster

I love original research and this is impressive!
You have tried to understand the development of the G4/LM carburettor.
The variations of the poppet valves are extensive.

I am an amateur with this, but I have a simple question ...
What advise, if any, do you give to repairers?

Many thanks for sharing your work with others.
I'm sure other folk will be interested in this.

Sincere thanks
