Side Throttle Stops

All descriptions refer to a front mounted rotary engine in a rear wheel drive car.

There are two types for downdraft IDA's: fuel inlet on engine side with throttle cable pulling from above the throttle shaft, and fuel inlet on the fender side, with the throttle cable pulling from below the throttle shaft. The manifold determines the carb orientation. It is best to have the cable pull, the idle speed screw, throttle stop, and return spring all on the same end of the carb. If this is not done, you will twist the throttle shaft, which can lead to various poor running conditions.
