Exhaust Co Value

[aerodyne]

Just checked exhaust Co values prior to balancing throttle bodies and resetting TPS, Left hand pipe 0.6%, right hand pipe 0.05%!! Anybody have any idea what the Co value should be and how close each pipe should be. Any advice would be much appreciated, Thanks.

Just been discussing this and the concensus was that you're wasting your time unless you either go for a raz and immediately test the CO or put a big fan on it.

The mechanic reckoned that on air cooled engines, if you allow them to idle before testing the CO, the piston crowns expand and reduce the CO almost immediately.

He reckoned 2.5? Don't know what the distilled wisdom of the forum is though

Cheers
