Well I am a bit confused on this one. 2056 dual Webers. Electronic ignition. New SVDA dizzy. Rev limiting rotor.
Pulled the tank to install SS lines and had a few problems with crimping the lines when putting the tank back but I think I have that worked out. Compression good at 130 plus on all. Timing set at 30 BTDC. Car runs strong up to exactly 4400 rpm and then it sounds like it hits a wall. Can run it long and hard at rpms below so I am not thinking it is fuel limited. Swapped out the rev limiting rotor with standard one but same thing happens. I am going to pull the tank again to be sure on the lines. Any other thoughts? |
