If it performed perfectly for months, and sometimes perfectly now (inertmitant issue) then is it not unlikely that its just an adjustment??
It could be that deposits have formed in the idle circuit. As the choke warms up and opens the engine goes lean. Turn your idle mixture screws 1/4 turn rich (counter clockwise, if you have a digital watch you'll have to figure this out on your own). See how it runs after adjustment, this literally takes a couple seconds of work and is easily put back if it doesn't work.
