Shut engine off experianced run on, starts and runs a few seconds then wont start at all
I have a 1967 Chevy Chevelle with a Merlin big block Chevy motor. I was driving to a car show pulled in a parking lot shut the motor off and I had run on culminated by spoke through Carb. I wouldnt start after so I towed it home. I cleaned plugs and changed coil it starts and runs a few seconds dies and wont even fire untill the next day? I have fuel it has MSD spark box. Do you have any ideas??
Can you check the MSD box to see if it's working properly?
I dont know how to check it, I guess if I start it and it fails again I can check and see if there is spark
Or just pull a plug and ground it good to see if you have spark.
I dont see a diode, however it has ran good for 3 years. I thought about the carb because it backfired through the carb before it shut down. I think there are some blowout valves in a Holley 4100 Thanks
To me sounds like carb.flote needle is leaking past and would cause the smoke from carb. After turning it off .
That leaking needle seat then would cause a flooding condition making it hard to start
