Hi Erik,
i remember a friend of mine tried Phillips “injectors” in our youth on a Norton twin: to our surprise and delight it started quite easily (i suppose the enormous amount of spilled fuel richened the mixture once we forgot to close the fuel taps). But everything less than full throttle was inferior compared to AMAL IIs.
It is an interesting device for 1/4-mile maniacs but certainly not for street use. Anyhow – it is desireable, collectable and will look nice on your workshop shelf but can kill your scooter´s engine before you can sort out the problems with partial throttle opening…
