@tomkuester posted:It's interesting to hear from you about your approach to things. I'm a do-it yourselfer and my Pantera has only been touched once by a professional engine builder. There is nothing on that car that hasn't been replaced or rebuilt over the years. I considered adding the third progression hole myself, with the help of U-Tube videos and advice from people like you it would have been easy. However on of the carbs had a worn bearing so one of the shafts would vibrate ever so slightly and activate the accelerator pump, dumping a bit of unneeded fuel down that tube. I could not loosen the screws on the butterfly valves without stripping them, so I decided to go new. I tried, i really did. Now I have four Webers sitting in a box and will probably still be there when I die.
My son is waiting to take over that car.
I wonder, how many Pantera owners are original owners?
You don't need to take the throttle plate off to change the bearings. They are under the throttle lever or the flat washer on the opposite side.
What you need to watch out for on IDA's is twisted throttle shafts. They are chromed brass and twist easily. That is usually a result of too much spring tension put on them by the throttle setup. They really don't need a lot of spring pressure to work right but some folks don't understand how to center the throttles and wind up with carbs that don't close all the way at idle after driving the car. So they think the solution is to put more spring pressure on the carbs?
The more you learn about the IDA's the more you respect the genius that went into them. They are incredibly simple and straight forward and totally un-Holley like. Gorillas need not apply. Maybe a ballerina would be a good match though?
