I have 69 johnson 85 hp and need to remove the orfices in the carbs but the tool i made needs more grinding and i wont have acess to a grinding wheel today so if the original tool to remove those is not that expensive i'd like to go get one. I called to my local marine shops but only thier mechanics have them and wont sell me one. Maybe an auto shop and if so what do they refer it as? any suggestions?
