My 67BGT had this unusual problem. After I bought it last year, I noticed
that the damper rod (plunger) would come loose on the rear HS4 carb. Even
after I tightened it as tight as I could get it, it still came unscrewed
within 5-10 miles of city driving.
I almost wrote in to the list to see if anyone had heard of this problem.
But I thought one possibility was the damper rod itself was no longer
straight, adding to the vibrations that were then unscrewing it. To test
this theory, I just swapped the dampers between my two BGTs. Well, a test
drive later, and the damper rod came unscrewed on my 71BGT.
The solution was to replace the damper rods - they were not overly
expensive, I think about $7-8 each. Its worth a try.
