I searched a few big hardware store near me and could not find a decent long brush to clean up my carbonized Johnson cd18 lower housing and parts
found something at Home Depot in the BBQ section… a nice long stiff bruh for a BBQ which I sqeezed into a long brush with real nice stiff SS steel fingers
see pics

January 27, 2023 at 4:34 pm #271863I have heard that “Eazy Off” oven cleaner works great in dissolving carbon built up in the exhaust housing.
January 27, 2023 at 6:25 pm #271876ok thanks I hear easy off is very harsh on aluminum but yes in that section of the engine it is not to bad …a good flush will do to remove it
I have used my new colonoscopy brush with success. narrow in places but OK I guess I kept a bend in it which I will straighten .
stains remain but all the carbon has been vacummed out incl PH exhaust area . 🙂

January 27, 2023 at 7:06 pm #271880In my typical restoration projects, I have always used Easy Off oven cleaner to remove the carbon buildup in the exhaust housing. It can be harsh on the aluminum, so I typically let it soak for no more than 20 minutes or so. That’s usually enough to soften the carbon deposits that can then be removed with a good flush from the pressure washer. Here’s a pic of one such cleaning.

unfortunatly for now my pressure tester is unavailable to test the GC but it… looks ok waithing for Spring 23 to test further and adjust the idle /fast needles
