Re: Timing for 302
There could be a few reasons why it won't idle down. First check to see if you don't have any leaks around carby base where it meets the manifold. spray some carby cleaner around the base help, if the engine speed fluctuates, it's leaking. Also, check if running a holley carb, see if the carby is tight but rocking side to side. the internal screws that hold the carby butterfly plate on work loose causing them to leak air. You will usually hear a high pitch noise near the carby. Timing could be a factor if advanced but if too far, you'd expect it to run warmer than normal and could be difficult toturn over. Hope this helps.
Someday, we'll look back on this, laugh nervously and change the subject...
