The very small orfice on the lower unit of my motor that is the speedometer pick up is clogged up. I used a very small drill bit and cleaned out as much trash as possible by hand. I think I have gotten as far as possible with a solid striaght tool but it is still clogged. <br /><br />What could I use that is flexible enough to make the upward bend yet solid enough to extract the material? I tried compressed air but it didn't work, any suggestions?
