Re: Bigger studs on my second engine.
the castings are the edges of the metal where it was pulled away from a mold and there are sharp edges,...?
and the ports are the 2 opening I guess, 1 coming in from the carb side and the other leading out to the exhaust,...? and just clean these openings up and smooth them out with a dremel,
this I assume is done with the block off the motor and the piton just hanging there for the time being,...? or do you just pop the head off and push the piston down and put a rag or something down in there and make sure you don't get filings or metal dust down in there,..?
this is the stuff we don't know, it's pretty much, "smooth out your port holes with a dremel"
just trying to learn,.....
