High CO2 reading

Postby Wyke » 03 Jul 2008, 21:05

1256 engine ( 1974 ) newish carb - MOT giving 10 % co2 - told it has to be less than 4 % .

Adjusted idling screw and richness at bottom of float chamber - screwed in as far as can go !!

Topped up dash pot and checked diafram.

Still high CO2 - any ideas ?
