hi I have a recently fully restored commando Mk 3 On initial start up I cannot get the bike to idle I have new Amal carbs and original airbox The bike starts right up after tickling carbs but I have to stay on the throttle to keep it running. It is like the idle circuit in not working As soon as I back off the throttle the bike stalls immediately. I double checked the timing I am using a Pazon unit timing is dead on I thought maybe a bad battery and changed the battery The engine also surges as I am holding the throttle . Any ideas would be appreciated Thx Drummer 99

Amal Premiers have been known to have machining swarf left it the idle circuit passages. So best advice is to remove them, then remove the pilot jet and idle airscrew and blow out the passages. Also it is now recognized that #19 pilot jets are better suited, so check what your carbs came with.

My mk3 will not run without a light throttle until I've ridden about 400 yards. Start on choke, choke straight off, ride away. Once it starts to warm all is fine. Nature of carb bikes.
I once rode about 3 miles having forgotten to turn the choke off. New plugs and never did it again.
