John, I suspect you have non-standard sheaves, and at the very least are missing the aluminum divider plate. The configuration in the C27 exploded parts draw show a 4 sheave mast head with a divider plate. I don't have any C27s to look at but this is typical to the C270, C25, and C22 construction.

Yet the opening for the single main halyard sheave is the same as the two jib halyard sheaves. I don't see anything to keep the halyard from binding up as it did. >From my picture, is don't see anything broken or missing. Is this a normal problem? John
