Easy Off........and a tooth brush.....old toothbrush not yer current one......Any ideas for getting this carbon out of the top of this jug? Stihl 4 mix...and I want to be careful with the valve seats which cuts out my normal pack it with Scotch Brite and spin it routine.
The white stuff came down in a blanket, flakes inches across,so full of moisture. About 4" so far and that fell in less than an hour. Mostly stopped for now with light rain falling.
Figure I'll warm the jug up a bit...spray it down and let it soak. Valves too.Mr Muscle is what the Colt Pielstik factory reps specified to dicarbon the piston crowns of the 8000 hoss V-16s......carbon on those was about 1/4" thick and it worked pretty good. Gotta let it sit and do it's work and then some elbow grease and they'd clean right up.....all 32 of them...…..arrrg.....
As Jerry said it will discolor alum...…but not really an issue in a cumbustion chamber.
