I just bought a 1971 norton commando 750 and I am having trouble getting it started. It has good compresson and spark, the battery is good and charged. It almost started on a couple of kicks, but thats as close as I have been able to come. I was wondering if I am missing something. Im not sure if there is a choke on the carbs, or what position the throttle has to be in or the compression switch. I have a full tank of gas and have primed the carbs to fill the fuel bowl. I do live in ontario canada and am not sure if is just too cold to have it start. Any advice would be greatly appreciated. Thanks
