I have done the FD switch over from the beginning ,this was what got the car started ,to report on start up difficulty it takes some coaxing from me plunging the metering plate a couple of times ,going back and turning the key over for 10 seconds with half a gas peddle to realize startup ,it then wont idle ,i keep it around 1200 rpms .The iacv looks orig but is different than my 1985 car ,strange. Ill clean it up and try this out next.
