Me being the dumb bad owner/purchaser I neglected to get the PO to get an emissions test. I take it down, and of course it fails. 403 Oldsmobile in a 77 Kingsley.
At idle the CO% was 7.23 with a limit of 5.5. Everything else was well wiyhin range.
I had done a new air filter and uel additiive to be on the safe side, but still not good enough.
So now I will do a quick tuneup, PCV valve, plugs, oil.
But what else can/should I do? I would think there must be some carb adjustment to be done for the idle carbons. Either that or perhaps a vacuum leak somewhere?? I am not very knowledgable in this area, so any suggestions will be taken seriously! Esoecially from anyone here in CO who wants to come by and lend a hand! LOL!
