Dan Baldwin Posted October 31, 2003 Share Posted October 31, 2003 Almost useless reply here, but I did use 2" SUs for a while. Tuned them per directions given in an old ZCar Magazine. IOW, didn't really tune them. Never measured A/F. Must've been running pretty lean, because the car used to start to run hot after a couple of laps at the track on warm days, and I'd have to start feathering the throttle. After installing 3x2 carbs, with the A/F in the right ballpark, the car has never run hot since. With the Jag carbs (HS8s), I just ran with the needles that were in them.

Guest NorCalZ Posted November 7, 2003 Share Posted November 7, 2003 I think I am running jag carbs on my Z but Im not sure because it came with them, how do i tell. The oil damper stick screw on top is much larger than the 72 SUs. Quote Link to comment Share on other sites More sharing options...
