Idon't brag I mostlyboast
So I go get the ride smogged (93 5SFE). Passes all the visual tests, all the emission tests well below max levels at 15mph and 25mph, BUT failed 1 functional test. Ignition timing is at 18 BTDC instead of 10, and I have to get it down to 11 BTDC. How easy is that to DIY, or should I drop more $$$ and take it to a shop for a 5(?) minute adjustment?
