Hello all, I recently rebuilt my 3 screw SU carbs on my 240z with the Z therapy kit. It was a good experience. At the same time I installed the MSA premium exhaust. I've noticed a very strong gas smell when driving the vehicle now. Is this normal with the SM needles? From my understanding they were overly rich during idle only? My 240 is basically stock, with the 2.5" exhaust and 280zx distributor coming soon. The smell is so strong I'm thinking of switching back to stock needles because it is so bad. I forget who I spoke to on the phone at Z therapy, but I asked if they were ok for a basically stock engine and they said yes. Secondly, when tuning them, one carb required 2.5 turns, and the other 3.5. Should I adjust the other float to make them exactly the same, or am I ok leaving it this way? Colten
