Carb problem..I think

[wyldhog77]

Hello to all. Here is the question that has had me pulling out my hair for a week......
I have a 65 coupe 289 auto trans. I have the 600cfm Edelbrock carb on a performer intake. This past winter, I broke down the carb, cleaned and rebuilt it. Installed it back with recommended bench settings, and it ran great. Now, it doesn't seem to want to start when it's warm, doesn't seem to idle right unless it warms up for 20 minutes. Once it's under load, it runs beautiful. I'm wondering if it's a mixture problem, idle issue or maybe something else. I'm the body guy, not a mechanic. LOL I appreciate any help/advice. Lou

As far as the hard start when warm, get yourself an Edelbrock heat spacer to go between the intake and carb. That will solve that problem. I would double check your choke setting as per edelbrocks recommendations. What is your curb idle right now? Did you go through the your idle mix settings? What other mods are done to your car? PM me and I'll try to walk you through it.
