73 modified tr6 with dual down draft Weber carbs.. Bought the car this way and would like to give the carbs a fair chance before swaping back to the ZS or buying SUs.
Engine has stock fuel pump that looks to be delivering 2 psi which I have read is not enough. Carter 4070 appears to be the pump of choice for webers.
Vac advance - it is hooked to the manifold - should it go to the base of the carb instead?
Spark advance at idle - is 12deg BTDC with vac advance unhooked a good starting point?
I can get the car to idle, rev in Neutral, first drive away is pretty strong and then misfires/backfires develop.
All comments welcome..
