did you remove that green tape?? seems that mine had a pretty good gap, but maybe i just need to wait till i have my blaster coil to put them in together. seems like it did NOT like my setup, it refused to even start on my SU carbs, but when i put the webers on it fired up, BUT was absolutely untunable.
I've seen some walk throughs(mustangs..) that show that this has a plastic gauge to set the gap, but mine didn't come with that. has anyone installed one of these systems>? (this is actually on my '72 skyline, not a Z, but i bought a Z ignitor.. they don't make one for the skyline) My L20 engine is pretty much the same as the Z, just smaller.
