Failed My Emissons!!!

[RoNx777]

I bought my car in DEC. 2001, I took it for itz first inspection yesterday...but it failed the emissions!!! They said the carbon out put was too high...almost double test limits dont remember the exact numbers...

Any ideas???

IIRC, retarding the timing a bit helps with the carbon output.

Hydrocarbons, carbon monoxide or carbon dioxide?

If it's hyrdocarbons, then retarding timing will help a bit, but you probably need a new cat.
