Engine cuts out

[John Mason]

Graham, It could be you engine is starved of air when you go around corners if there is a small piece of dirt in the jet accessed by the brass screw on the bottom of th carb. This jet allows air to bypass the closed throttle butterfly when your foot is off the throttle. It could be that centrifugal force moves this speck in of dirt enough to stop th engine. Rather than removing the jet that which can be awkward and can damage it a can of carb cleaner is a better option.
