Well temperature change and the pinging returned. Well nothing else to do but mix fuel and prepare to change the cam out.
Before you go yanking the camshaft out, you might want to call Cliff, since he built the carbs you are working with, give him your symptoms and motor specs and see what he thinks. He is also an engine builder and may have some additional insight.
Ya I have been communicating with him. He along with several others believe the cam is to small. The tight LSA 110 builds to much pressure in the cylinders. They also believe my CR is more around 9.6-9.7 which is much more then the 9.2 the builder stated. Cliff and others seem the XE comp cams are better for low compression motors. They think the only fix is to switch it.
