Been having trouble for quite some time now starting my car after it's hot. I have a '72 340 duster with an agressive cam (unknown). These are the symptoms i am having.
-Car starts perfect when cold, but does smoke (blue) for 1-2 min.
-After 1-2 min., no blue smoke - car idles around 800 rpm very nicely.
-After taking car for a short ride, engine is shut down.
-Let car sit for 15-30 minutes.
-Try to restart...engine seem like it wants to immediately kick over but doesn't. Sometimes i hear a quick knock or ping.
-Try to restart again, this time I need to crank the thing for a long period of time before it faintly comes back to life.
-Sometimes need to rev motor to get it back to normal idle speed.
-Once I do get car to turn over, I can now shut it down and start it right back up with no problem.
Though I was boiling fuel, so i put a wooden spacer between the carb and manifold. Changed the coolant and thermostat. Car stays very cool...gauge reads below halfway. Carb stays cool. So this can't be the issue. I have my initial timing set at 16 btdc, total at 34. My timing was set at 18 btdc before and still had the same issues. I did change my plugs, to rule out fouling from the oil (blue smoke). Only one of the plugs looked like it had issues. If anybody can shed some light on what this could be I would greatly appreciate it.
