I purchased a duetz tractor (4006d) with the f3l 912 air cooled engine. The engine starts right up and doesn't smoke but has a metallic pinging sound when it runs. Best I can tell, the sound is coming from the top of one or two of the cylinder
sleeves where it meets the head. I'm thinking the piston is slapping the valves. I read online that there are shims that need to be used so this doesn't happen. Can someone school me on how to measure what size shim is needed? Does the
shim go between the cylinder and head or do you have to pull the piston and put the shim under the cylinder insert that goes into the block?
