In the last couple of weeks I sent a couple of questions about a dead Pertronix and loosing power above 3500 rpm.
Just thought I would report back. The Pertronix was fried evidently I flipped the wires around that go to the coil and burnt it out . A new unit fired it right up. The loss of power was a bit more elusive. (The car has twin HS4) I was convinced that the carbs were adjusted right. The engine picked up very slightly in rpms when I lifted the pistons. The rpm increase seemed to be about equal when lifting each of the pistons. So I had tried looking else where. Finally , I got the ColorTune out and installed it in the car (once on #4 and once on #1) and adjusted the carbs until the flame was yellow and then back to blue ( I left just a little yellow in the flame). I started to take the Spit out for a test drive and noticed the front carb was leaking from the fuel bowl where the jet goes in. I tried tightening it and it just leaked worse. I discovered that the seal was split. (Is this a common problem or am I doing something wrong? I have had this happen to both carbs in about the 1 1/2 that the SU's have been on the car). Anyway, I finally got the car out for a test drive after replacing that seal. The car ran great. So the loss of power was that the mixture was too lean.
