I can't tell for sure what model it is, but I'm pretty sure it's not a 32/36 since it's not progressive (the meshed gears open both barrels simultaneously). Mine runs fine and I can't really complain. If I had the option, I'd go for stock, but it runs fine and the electric choke actually works much better than I expected. I used to worry about it since I always had to fiddle with my manual choke to get it running right (vacuum leaks), but I literally never even think about it anymore.
Mine is also mounted 90* off, so that the linkage is toward the firewall and doesn't leave enough room for a picture.
On my 32/36, there are stampings on the red box in pic 1 that say "32 36 DGAV33xxx"
Pictures 2 and 3 are of the stock linkage. I used the complete stock linkage and just had to 'customize' the throttle lever arm on the carb (cut n weld) to get the proper angle.
Pic 2 is the pivot on the firewall. I couldn't tell from your pics exactly where everything was hooked up, but this is the stock setup.
I'm guessing that the shaft under the yellow arrow is what's hooked up to your carb lever?
In the stock setup, it (now red arrow) goes to another pivot mounted to the block but hidden behind the exhaust manifold in pic 3. Then there is a linkage that goes vertically up to the carb (yellow arrow). The throttle return springs are connected to the hidden pivot on the block.
Hope that all makes sense. It looks like the PO omitted the second pivot point on the block and went straight to the side of the carb. The little pin that goes through the throttle lever arm definitely looks stock, so it looks like the stock linkage arm (yellow arrow in pic 3) was used, but in place of the intermediate parts.
HTH,
