Hi Alex

My BT7 has HS8 carbs ex XJ6 Jag so we were flying fairly blind as regards 
needles (biased needles with 100 jets).
We used a Snap-On exhaust gas analyser which has a pickup and a rubber hose 
which we fixed in the exhaust pipe and ran the hose back to the cockpit.Went 
for 20km(12 mile) drive and worked perfectly, gave us A/F ratio (good) as 
well as CO (CO2?) levels (which I dont care about)
