So I have to wonder if desmogging is illegal if the end result is better emissions. For instance if you go to a fuel injection system that vastly improves the em missions of your vehicle and you pass a smog test are you still in the wrong?

Maybe I just need to wait for @FJ40Jim to work his magic on my carb...Hey guys - question for you. I just finished my desmog with parts from JimC. All has gone fairly smoothly. I'm still awaiting a rebuilt carb and recurved dissy from him, but that may be month more. So in the meantime I'm doing what I can to get this running well.
Started up today, 5degrees F, and ran for about 10 minutes. It was a little rough. I've adjusted the timing. Then I noticed some loud muffler noises and looked down and saw the catalytic converter was red hot!
Thanks for all the help guys!!
- What is causing the red hot cat? Just way too rich?
- Would it be beneficial to remove the cat? (Think I damaged it?)
- What is the ideal timing on a desmogged rig? 7 degrees?
- Why is it running so rich? Stock carb, with screw still capped from factory. (it was running rich before desmog, but I never noticed a red hot cat)

It is illegal to modify emission control equipment.

Has anyone here ever bypassed the air injection but keep the EGR intact? I'm currently in the process of replacing my smog pump with a used one purchased from another MUD member. A slightly leaking power steering pump is probably the culprit that destroyed the old air pump, and now I'm scared to put the used smog pump in and have it explode as well. My plan is to de vein the smog pump, install it, and cap off the air injection system until I can resolve the p/s pump leak but leave the rest of the emissions system intact. My rural county in CA, doesn't require yearly smog testing so there wont be any issue there but I don't want to scrap the whole system in case the rules change, plus the emissions system in my truck was functional up until the smog pump locked up.
