Bsa B40 Trials Vm22 Mikuni Jetting

Hi all

Mikuni VM 22 carb on Tiger Cub probs

 

When cracking the throttle wide open from a near standstill, the bike has a massive flatspot, then picks up. Now and again will stall after descending a hill.

If I were to slowly roll the throttle on and off the bike is fine. Is this normal for a cub / this carb.

 

Is anyone running this type of carb successfully, and what have you had to change on the carb to get it to run.

cheers
