Failed Emissons 88 Fox Pls Help
The first time both HC and CO were high. I adjusted the timing down to spec, 6 degrees, and I turned the screw on the side of the intake in about 3/4 turn. The HC came down to just about spec but the CO went up even worse. I assume the HC was related to timing but I realize I don't know what the screw on the side is for. Any help would be appreciated.

Re: Failed Emissons 88 Fox Pls Help
the screw on the intake is for idle speed, lowering the idle usually makes the CO run a little richer. Mixture is adjusted at the 3mm allen screw between the fuel distributor and the air boot. You might want to take this to someone who knows CIS-E fairly well. They can adjust CO% and check O2 sensor operation at the same time.

Re: Failed Emissons 88 Fox Pls Help
Thanks for your reply. It turned out to be that the cat was hollowed out. A used cat solved the problem.
