recently got my trueno going, its running a bluetop twin cab 4age, any way she was idoling real rough and just died when i gave her any revs
had a poke round and found the dissy to be real loose

so what sort of options do i have in the ways of replacing it? the existing dissy looks nothing like a standard bluetop dissy so it leads me to believe it might be a 4k dissy modifed or something? ive read a little bit about how these can be used on twin carb 4ages so i was wondering what is invlolved in modifying them to suit?
any help is greatly aprecciated, wana get her running asap so i can hit the track
cheers
