Innovate Motorsports. They make kits for data-logging the AFR against things like throttle position, MAP and RPM. Not cheap but it is the only way to tune an aeroplane engine.

Rab,
Thanks for that. As you say its pricey, but so much easeir than doing AFRs as I am by measuring fuel and airflow! This may make another thread.
Morris Minor, the car of the future. One day they will all look like this!

I'm back, after 15 months of cycling and 30000km, and back into the minor

I had the car running on my modified aquaplane manifold (twin 1 1/4") before I left. That's back in storage.
I did however come across this set up recently, so will be using these

Quite nicely made, I'm guess these were made by a tuning house rather than a back yard mechanic
Currently waiting on a couple of gasket kits and a different choke linkage to show up. have stripped them and had them ultrasonic cleaned. should be nice

(funnily one carb had a brass piston, the other the usual alloy. I bet that made them hard to tune)
