    Here’s some common and not so common taps and dyes I keep nearby when working on the smaller OMC classics. While everything is apart, I like to chase all of the threads to remove any gunk or corrosion. That makes it a whole lot easier when going back together. The 4-40 is used for carb butterfly screws while the common 10-24 is used mostly for exhaust covers, intake manifolds, and mag plates. The 6-32 will clean up the threads on the mags adjusting screw for the points. The special order oddball 12-28 is used for the tiller grip screw and 1/4-40 is used for most carburetor mixture adjusting screws. The 12-28 comes in real handy as lots of tillers I see have mangled threads in them.

    Some OMC carb butterfly screws are 5/40 thread. A not so common size.

    Mumbles – you are so right regarding having all of these taps and dies. I recently had to go pick up a 4-40 to clean up one of the carb butterfly screw holes when I rebuilt my RD-18 carb. I needed the 12-28 tap on another rebuild and although I didn’t have one, I was able to borrow one from a neighbor who was a machinist. Always good practice to clean up threads during the rebuild process.

    Living in a small town I have a problem finding certain tools. Tried to going to the local machine shop, but they just grunted at me.
    I mostly have to order them from the innerweb.
    My go to is Mcmaster-Carr.
    They have everything we need.
    If you don’t mind shopping online.

    Fortunately my wife’s grandfather was a Singer Sewing Machine repair man (person for CA) and she (I) has inherited his machinists tool box that has a wide variety of taps and dies. I also have my great grandfathers machinist tool box. Tom Weatherston worked in the machine shop for Pierce Arrow in Buffalo, NY. Oh, the things these two gentlemen must have known and seen…

    I will need to go through both boxes and “liberate” the tools that are most commonly used for my small collection of antique outboard engines.

    Thank you for the list Mumbles!!
