My 125 has started thumping when under way. It is normal to about 3500 rpm then every few seconds it makes a audible bump as well as it seems to jerk a bit
When starting my force 125 when I push in the to activate the choke the choke engages and stops the engine from cranking. And if I push in on the key first the starter won’t function. Why is the choke interfering with the starter
