Long subject line. Here's the story. Ever since I've owned my 74 GTV, I've had the same Spica pump. The car has always run great, even after a fresh Norman head and 10.2mm cams 6 or 7 years ago. A short time after the rebuild, my mechanic said, "Y'know the TA mount is all buggered up. The TA is only held on by one screw. I tune it the best I can." I inspected it and one screw had snapped off at some point in the distant past. Someone tried to tap a new hole just off to the side, but that didn't work out so well for them, so they left it with only one screw holding the TA on.
I recently started thinking about this again because I never get more than 135 miles on a tank of gas. I have never figured out the mileage, but with an 11 gallon tank and putting 9 to 10 gallons each fill that makes something like 14 or 15 mpg. Not really right for a Spica system unless something is amiss. Could a poorly seating TA contribute to bad gas mileage? I have a spare pump that is on the engine I had removed from my Alfetta when I put in the TS into it. Should I be thinking seriously about sending this worn pump out to Wes and installing it on my GTV?
