George Asche Dual Carb update pic.

One of the interesting differences between the 1934 model and all of those that followed is the design and location of the throttle actuator. On the 1934 model there is a rod that goes from the gas pedal all the way across to the passenger side on the firewall in the engine bay. What this means is that the later model throttle actuation that goes over the top of the engine block head to the carburetors it's not how the early model works. The 1934 model has an onboard the intake manual actuator that not only attends to throttle acceleration but also provides the means for the dash mounted throttle adjuster to work as well.

 

The vast majority of George Asche installations that I have seen both of the later accelerator actuators and also they do not appear to support the dashboard mounted throttle adjuster cable. I wasn't willing to give those up so I went about the Asche carb set up a bit differently. I actually used both sides of the new intake, with the linkage that moves both carburetors in synch being on the engine block side and I use the provided pad on the passenger side to reconfigure the whole standard actuator including the dash throttle in a brand new design. I thought that resulted in the nicest presentation and preserved all of the features of the original. Now you can't use the original throttle actuator and the reason for that is the original one pushed up on the carburetor and the one that we use for the Asche model pulls down. 

 

When I finish this whole thing I'll do a full feature right up thread. What you see here is are 2 photos of the fitting and testing of the new linkage. For those of you who may have read my piece about accessing the valves by taking all the intakes off, that was done originally so I could get everything out of the way and remount the Asche intake to test fitment. I originally decided while everything was off I would redo the valves. Anyway the new design will now be taken from its original aluminum modeling you see here, to pita to make stainless steel throttle actuator. Astonishingly. Both the choke and dash mounted throttle cables along with the firewall actuator rod all fit perfectly. That never happens around here and required us to sit and stare at the intake because we just simply couldn't believe what we were looking at. Anyway it all is a step in the right direction. Just note, the bright large diameter tube in the lower left hand corner is the vacuum line for the 34 and it's just sitting there disconnected.
