2 out of 8 plugs fouled rich.

Sorry for not getting back too you all,I put on a new cap and rotor put 2 new plugs in went to a cruise in about 30 minutes away,check 3 and 4 cylinders,clean,I switched from 160 thermostat to 180 yesterday too.
 
Any suggestions?

I haven’t bought plugs in awhile. It’s getting harder to find them for older engines. Champion and accel has been good to me. The accel shorty will work but I would look for the normal length first if you have stock manifolds. The shorty is good for header applications.
Don’t like auto lite either. Look up your heat range that came with the engine and try to make sure they are correct. If not they can foul or run too hot.

That’s a good forum topic to post or search since I bet that was a discussion in the past.

Might even be a call to Mancini or 440 Source to pick their brains.
