Starts fine when hot, cold DOES NOT
 

i have an 85 gsl with 12a. has rebuilt stock nikki, emissions removed, rb header, silencer, and power-pulse muffler. ive had it out this year for a month and a half. car started great, *choked and a touch to the key* :) every morning until 4 days ago. turned over for like a minute before even the slightest pop and choke and some pedal make it worse. has been getting worse every morning. BUT starts fine when its been run, even starts after 8-9 hours sitting while im at work. WHY the hell wont it start in the morning! its driving me insane. drives great and pulls great on the highway too. milage is 116k....

Ignition has been checked-FINE
fuel system has been checked-FINE

is this carb related?
