See if you can get a long thin screwdriver etc and see if you can rest it on lifter body while someone turns crank slowly for you to see if the lifter is still lifting as much as it should(to rule out cam lobe). If it's popping through carb at idle, I would bet a lobe is wiped.



a collapsed lifter that isn't opening the exhaust valve fully, would act the same as a fully functional lifter on a wiped lobe that isn't opening the valve fully.

could be either one at this point, but if you pushed down on the pushrod to keep tension on it, and could feel the lobe of the cam moving the lifter up and down, the cam just might be ok.
