Looks good. Don't know what it is about the Wrights, they have such unique designs.
I just finished a C40...and was glad to see the Tilly HL instead of the Carter. Just missed a C50GS bottom end. I assumed the upper parts from the C50 would work.
Turns out the last of the C40's did come with a Carter NRD and it was the later version of that as well. It uses different pump check valves and a completely round metering diaphragm as well. Turns out this later Style NRD was the carb that was used on the C50SG saw's as well.
Below is the last style NRD on the right. Only 4 screws to hold the metering diaphragm cover in place in the recess in the carb body and a round diaphragm. The C40 used the same later NRD but a different carb number as the fuel inlet is positioned differntly.
On the right is the prior NRD that was used on the C50 direct and C50G if I remember right.
