I use cr's on all the customer racers,
they are prone to flooding, usually just fine dust in fuel is enough,
always use a clear in line filter, do not rely on the gauze around fuel tap. make sure float valves are good
make sure floats are good and set correctly, my guess its just dirt, so many customers bring them to me swearing they've cleaned them out, and the tank, and there is still stuff getting through, the clear in line filter give a visual indication as to whats getting through.
