Brettm57 Posted November 29, 2005 Share Posted November 29, 2005 I'm getting ready to do an overhaul of an EA-81 and need to clean the carbon from the ports. I'm looking for suggestions to do that without damaging the aluminum. My first thought is to soak them in carburetor cleaner. Is there a better way? I'm thinking a standard hot tank will damage the aluminum, but maybe not? Thanks. Link to comment Share on other sites More sharing options...
rallyruss Posted November 29, 2005 Share Posted November 29, 2005 sea foam works good. but oven cleaner is the best. It melts carbon deposits really well. old school hot tanks are bad for aluminum yes. Some of the newer heated sprayjet type units have better soaps that do not harm aluminum. I would talk to your machine shop and find out what they have. Link to comment Share on other sites More sharing options...
