My Locost has a 1977 1300 x flow and the test is due on the 25th. Is the emissions test for that age of engine a simple visual test or is it more complcated?

Just a visual, but make sure you have proof of engine age. Ford will send you a letter if you ask them.

Are emmisions tested for post 94 engines then? (i thought the post 94 thing was for testing lambda)
