so far i have new plugs, oil and filter, fuel filter, air filter
replaced all vacuum lines
fresh fuel
any help??

ive heard using a few gallons of methanol hydrate helps?
removing the air filter helps a little?
playing with the timing as well? which way though?

any help greatly apprecaited..

 

Set the timing to factory specs, and adjust the carb so your not running as rich and you should pass. Looks like your catalytic convertor might not be doing a very good job anymore either.

other then what you've already mentioned, i've heard, run a tank of premium through it, have it good and warm, and try to go on an overcast day.
not sure if these really work or not, but not very much to try them.
