Also the 50 carbs were 25mm throats,do you know what size the 70s are? Got the freinds with stingers total attention.

when you open the throttle, this is what ya want to happen in order for best results. when ya hit it, carbs crack open Then All the timein advance drops in

then the carbs go to full, full blast. loose the choke plates
