Re: Stuttering
was it doing it before you took the carbs of and cleaned them? as in is it all back together right? vac line not split? fitted correctly? when mine done that is was running filthy rich as it came onto the main jets. 
the older i get,the faster i was 
Re: Stuttering

Coils, spark plugs and caps are next.
It's not falling off, it's an upgrade opportunity.

Re: Stuttering
Are the carb rubbers definitely on correctly and clamped up fully? It could be air getting in there.
