I've read the posts, looked them up and watched the "How To" videos. I have an 84 evinrude 35hp, that has not had this done before. Is there anything that would cause a problem by doing a decarb to an old motor? It works great, been well maintained, except for this. I don't want to run something through it that might screw it up. ("If it ain't broke, don't mess with it" theory) I have everything I need to Git 'er dun, just want to make sure this is OK. Thanks.
