im failing on c.o., my original test it was only off by .42
then i messed around with the distributor to try and retard the timing but that put me off the mark by 2 full points in the wrong direction. where do i go from here?

First, put your distributor back where it was. Then, run the tank empty, and fill it up with the expensive 93 octane, and pour in a pint of 100% rubbing alcohol. This should lower your ignition temperature a slight bit, and should be enough to pass. That is, if the Co is the only thing you're not passing DEQ for

also get an oil change to that may also help. and be sure to get the engine good and warmed up before going. the colder it is the richer it will run.

well i finally passed. i had the tank down to about a 1/4 and i poured a bottle of 108 octane in and also leaned the carb out about a half turn. i ran it pretty hard on the way there and blew right threw. Actually took a full point off of the c.o.
