Carbureted LSX forum - Hard starting when warmed up?

Hey guys my 6.0 starts fine when it's cold but I warm it up and shut it down for 20minutes it turns over forever before firing. I have to check and see what I have programmed in for timing while cranking. Do any of you guys have this problem when warmed up? What's your cranking timing at?

My base and idle are at 20*, never any starting issues. Maybe you are running fat enough that it is taking a bit to burn/dump the left over fuel so it will fire again.

How about your 0 to 1000 rpm timing?

You defiantly need less timing when starting up. My boss runs a 69 Camaro with a pretty hot 408 13.1 cp and he had retared the shit out of it so itll start when its warmed up. Side note.. Runs 9.30s all motor
