350 Cold Start issues?
I have a 350 bored .30 to a 355 with MSD ignition. When i try to start it up, it kicks revs a bit, then dies.
It does this a few more times, and then starts up and idles fine between 500-1200 RPM. I'll kill it then wait a few minutes to a half hour and it will start up almost instantly.
What could be causing this? And how can i fix it?
-Thanks

From your other post:
"750 CFM Carb w/out choke"
That's what a choke is for.
If it starts well cold without a choke, it is not properly tuned for operating temperature operation.
