I just finished installing a new carburetor from MMI on my early model A4. Got all the bits from Ken needed to make this work. I’m replacing an old style carburetor with a new one. My only problem is the throttle cable attachment. The old carb had an adjustable arm which was set forward to allow the cable assembly to travel more forward than the new carb arm allows.
The obvious answer is to simply re-mount the cable to accommodate the difference. However, there are two issues, one, it’s not possible for me to remove the bracket without unscrewing the large bolt on the rear of the engine. Which I am afraid to do lest I create a new series of problems.
But more importantly, even if I could adjust the cable mounting scheme, the connection at the end of the throttle cable would then be in direct contact and rub against the rubber fuel hose connecting the “U” shaped tube from the fuel pump (electric) to the carb.
I am at a loss as to why the new style carburetors do not have the arm adjusting nut. That would make this a 3 minute fix. Instead I am dead in the water. Am I missing something?
Is there an adjustment for the new carb arm angle that I am missing?
