rvandivort,I bought an ms1 with single ign output. I already have an 83 turbo dizzy,I needed to know about the cold start. If I read Naviathan"s post right,I can use my aar without the cold start valve. Just about have all parts needed. Would still like to have someone in the San Diego area,who has done the change,to help if possible.I have a shop to use and will pay for gas if needed. Again,thanks for the replies.
