Thread: Random Plug Fouling After Engine is shut Off..??

Tweet

Ok This one has Me really Stumped!!!, After awhile when the Engine is shut off (Will be running fine before then) then say maybe few Hours Later when I go out to start it I've lost a Cylinder, this has been an Ongoing Saga for about 6 months now, I look at the plug and it's Fuel fouled. (Random Plugs, some wetter then others)
The Engine is a 347 Stroker.

1.Probe Aluminium Pistons
2.Speed Demon Carb (750 Factory Jetted 76/83)
3.TrickFlow Twisted Wedge Heads (Stock)
4.Victor Jr. Intake
5. Camshaft Duration is 224° Intake and 232° with 542/563 Lift.

O yea and this only happends after it is restarted, never happends while just going down the road, The Engine is Brand New will all new Electronics MSD Billet Dist, etc,etc... My only thought is maybe too cold a Spark Plug..?? Carb Baseplate Leaking Fuel then Hot soaking..?? I went 1 up From what TrickFlow Recommends on Heat Range for the spark plugs.
Any help or Suggestions Will be Greatly Appreciated..!!!
