omc does make a gasket remover, mite be the same as permatex.(metal surfaces)<br />dont know if you can use it on all surfaces.<br />if its the black poly carbs, the gumout carb spray worked for me.<br />but what ever you do be careful not to nick or scratch mating surfaces.
Usually ya' shouldn't need any thing to remove the manifold gasket from the carb. Just scrape it off and if you have some hard spots, soften it with carb/choke cleaner and use a small wire brush to remove the hard spots.
For those stubborn, hard-to-remove pieces of gasket, I use a die grinder and Scotchbrite pads.<br />In fact, that's what I do to all the metal sealing surfaces.<br /><br />c/6<br />Hooty
