Getting rid of learn burn.

Best to swap out the LB before it fails. My 85 D150 smoked the lean burn and stranded me in Redding CA for three days. LB control units arent really available, and no shop could help me because of CA emissions laws.
In the end, the parts list was for a '74 D150
Distributor
Ignition control module
Ballast resistor
Carburetor
Wire harness w plugs for dist & ecm

reviving old thread:

I have an 83 down here in San Jose, taking off the Lean burn system but still need to get the emissions test done. Did yours pass the sniffer test after the new distributor and Ignition module?

I'm leaving the cat on but was wondering if that's all I needed to overcome.
