Thanks for coming back, I have a 622 R300 22mm. I'll give it a go to see how it is on mine.

Hi MrMud, I have just brought a Triumph Cub Trials, what carb are you running on? mine has an old 376/272 Monoblock which was for the scrambler I believe, It cuts out when I blip the throttle and someone suggested I should put a Amal 600 concentric 24mm on it to get a smooth tick-over and a good pickup.
