Plugs are showing lean and I’m trying to figure out the cause.
I’m running a GM coil with new leads (resistors removed) and iridium plugs. Would the iridium plugs make a difference in showing a lean condition?
75, 118.
Valves adjusted.
Checked for air leaks, none.
Carbs should still be sync’d.
OEM airbox, fairly new air filter.
Mixture screws adjusted.
The engine seems to get pretty hot.
Up another size on the primary?
Thank you.
