The results of the SVA test were..

rpm- 2688
co - 0.03
hc -104
lambda -1.08

getting the lambda low enough without the hc going up was the problem . I also found that the lambda was a bit unstable and the exhaust was "burbling" a bit.I am going to a garage on monday to set up the carbs first ie balance etc.. any help would be appreciated!!

an air leak will cause high lamba,make sure its well sealed

Seal the exhaust with silicon sealant, it works realy well once it has smoked a bit.

dont use exhaust paste gum gum. It ate my exhaust on my mondeo. its acid based.
