I am 0-2 on my first 2 emissions tests. Looking for some ideas... Me no speaky carburators! :
It is a '78 2f in an FJ40. ALL smog equipment intact. It passed all of the visual and equipment tests. On the sniffer, it passes everything BUT loaded CO. The limit is 1.5 and I am over 5.5. CO at idle is .5.
It was worse the first time around, failing both hc tests as well,but after adjusting timing, and the idle, the hydrocarbons fell into place.
So, I am FAR from a carb. expert, but I am thinking there is too much fuel getting into the engine when you come off idle. Should I be checking to see what jets are in there? Does anyone know wich ones are SUPPOSED to be there? I think ths vehicle spent some time in Colorado, so maybe its jetted for altitude??
Thanks in advance for any sugestions!
