OK, fail the emission. CO is about 4.5 above limits at idle. I need help before spending $$ with a mechanic. Here's what I've done so far:
1. changed plugs
2. changed wires to 8mm
3. spray clean the carb
4. changed oil
to do list:
1. caps and rotor on order
2. replace air filter
What else do I need to do? The previous owner had the idle too high so I adjusted down. The computer reads about 610 - 630 rpm during the test. Will adjusting the idle up to like 800 rpm and changing the air filter will bring down the CO? Thanks for any tip(s).
Sorry, it's a '78 with the F engine.
