Chad Phillips or anyone else who knows the answer.I have a first version EB pre-race .24 Ex Tech engine that came with no shims. I bought a new version II .24 Ex Tech pre-race engine from Amain Hobbies that came with (1) silver 0.006 thousands/0.15 mm shim installed. I bought the version I EB engine that was disassembled by the previous owner and I want to make sure I have it shimmed correctly. Does anyone know if the first version .24 Ex Tech EB Mods pre-race engine come with a 0.006 shim from Ed? I hope that made sense. Thank you in advance.Scott S.
