Hi -
I'm a newbie embarking on an overhaul of our functional 1957 Johnson 3 hp JW-13.
There is a large amount of oil and carbon buildup on the piston tips, throughout various chambers in the engine block, on the exhaust plate, and on the head.
My objective is to replace every gasket present on this motor, from top to bottom.
My question is: What is the best way to safely remove all of the oil (from the places it shouldn't be) and the carbon buildup? I want to make sure I don't do any damage and necessitate further repairs. I also don't want to take apart more than I absolutely have to in order to reduce the risk of putting it back together improperly.
Also: What is the torque specification and tightening order for the bolts around the head?
Lastly: I've read conflicting information on whether any silicone is required when reapplying the head gasket - do they go on 'dry' or with some other product? Does this apply to just the head gasket or all the gaskets in the engine area?
Thanks - Once I solve this I'll be heading lower! Lots of fluid coming out of the powerhead adapter gasket.
