Spark plug recommendation for carbed '73 911S

[Neilk]

Hi,

I'd like to change the spark plugs in my car this weekend. What do you guys recommend for a carbed '73 911S (2.4l)? What would be the proper gap for the plugs?

W5DC/B8-ES / 911T track / 911S high-way
W4DC/B9-ES
W3DPO / 911S track
Coldest

What plugs should I use for a somewhat rich running carbed "S" ?

Thanks!!

The stock MFI runs rich as well...So, any of the above should work. It's your determination on how hot or cold to go, based on your climate, your driving habits, and what you feel works...
