Does anyone know how the numbers work on a fuel pak? Does a bigger number mean a richer mixture or is it not that simple?

Not having any problems with the ones I have fitted but I do like to fiddle....

 

I tried asking them once about those numbers on the fuelpak and the tech wouldn't tell me.

 

No surprises there then....I have been comparing maps by putting different details into the site and I think I have a handle on where abouts in the map things work but some numbers are - numbers in some maps........I might borrow an air fuel meter and have a play.
