Drilled the broken intake bolt and removed with an extractor; managed not to damage the face or bolt hole. Right wing tank was still holding pressure; removed pump and balloon. Removed left wing tip in preparation to running conduit for GPS antenna and locating them in the tip. A test with the antenna in a fiberglas structure (unfinished wingtip from Jack Keegan's propjet) showed that they should operate under fiberglass; will test again under gel-coated tip. Ran 5/8" conduit through wing forward of spar; will do attachment and routing in next building session.
Finished fabricating the spark plug wires for the lower left side; straight connector at plug and 90 degree at coil. Used spacers and clamped to engine mount to finalize mounting. Utilized supplied wires for the upper left set; fabricated a couple of tabs to fix the routing over the cylinders with spacers. One tab simply spaces the wires and fuel purge cable from each other. Used one supplied wire and fabricated one for the upper right side; positioned a space to be held to the fuel purge line with a clamp when it is installed.
