Standard clearances........ although in my old age I've forgotton what standard is?! I'm sure someone will be along to tell you. If not check the Haynes

[gardner51]

Some people do .20 .20. Others do .20 .25

Ex 0.20, In 0.15. Is what it should be for a std C1J, despite what the Haynes says.

Look here for more info:
