On the idle down shutting down... You are likely need to adjust low idle needle and low idle speed on your carb.
On the throttle up jumps..... Something is at issue with the governor and/or the linkage, cable and springs. Could be something binding or the governor is not set properly.
Moderator: I note the OP has created two posts on the same subject. Is it possible to combine the two in one? Thanks
