[DeTomaso] Sparkplugs

[Henrik Svensson]

Hi

I would say close to normal with a slight dry failure. After 4-5 hours of normal driving it's getting hard to start. Cleaning the plugs make it fire instantly.  

Sounds like I have to move my focus from the plugs and start looking at the carb...

Henrik, 
How do your plugs look compared to the photos on the page: ?

How long (how many miles / km) do the plugs work before you have to change them, and how are you using the car?

If the plugs are having to be replaced soon after installation and you are doing normal driving I would think the mixture is the problem.

 Hi

 I'm looking into my starting problem and I have reached the sparkplugs.

 I actually have no clue what plugs to use so I'll send a general
 question here.

 I have a 393 stroker with AFD 4v heads and MDS ignition.

 The plugs I use today is NGK BCP 6ES.

 When the plugs are new the engine fires without problem. But after a
 while the engine gets harder to fire up.

 The plugs does look ok to me when removing them, just a very little
 sooty but not as much that is should give me problem when firing the
 engine?!?

 Any recommendations regarding Heat Range or electrode gap?
