I have had a few of the ,049s and .15 ones and just got another off Ebay was described as a .049 but when i got it was a .09 That makes it complete collect but they all need a part made or a little work to get up and running .049 .09 .15 The transition sounds nice do you think better that the Carburetor ?

Friend Eric! Congratulations on your new acquisition, it would be great if you post some video here so we share!
You ask me an interesting question ... I have my point of view and here I will try to reflect it.
All systems, carburetor, throttle ring, or accelerator bar have their virtues and cons.
I think that for very small motors such as .010 and .020, the ideal thing is the acceleration ring, it works very well and there are no complications in the installation or in the carburation, neither is it necessary to pressurize the tank or fuel tank , only the necessary adjustment of closing of (lumbreras) exhaust exits and everything marches perfectly, surely low cost of manufacture, low weight added to the motor.
The accelerator system "bar" is very new to me, very efficient so I see, I think it is a very good option, only that it is intended for a single line of engines "The Medallions", by the type of spray bar.
The carburetor is finally more complex, requires more attention in the tuning, it is almost always necessary to pressurize the tank or fuel tank so that at low turns, the engine receives the fuel needed to run.
The carburetor in low displacements such as .010 and .020 for me is completely replaceable by the throttle ring, what's more, I like the accelerator ring more for these displacements.
