Cable Management

Fabricated a quick stand-off bracket to help route the throttle and mixture cables to keep them from chaffing on fuel lines.

Canopy Hardware Fabrication & Installation

Fabricated some brackets to attach gas struts to hold the canopy open along with some canopy safety catches and handles.  Used 40lb 9.65" extended, 3.54" stroke struts from McMaster-Carr.

Rough Idle Troubleshooting

Spent some considerable time troubleshooting a rough/loping low idle.  Ran fuel flow tests, cleaned all the fuel injector nozzles, checked for bubbles in the fuel line from the fuel pump to the flow divider, inspected all plugs, and replaced all ignition cables on electronic ignition side.  Traced it down to the vacuum advance on the electronic ignition.  At low idle, the high vacuum was sensitive to the pulses from the cylinder cycle since the vacuum port is so close to the intake valve on the cylinder.  Ordered a .004" Snubber from McMaster Carr and put that right on the vacuum sensor port, and the idle smoothed right out.

Spent some time making brackets and cleaning up the ignition wire routing while I was at it.

First Engine Run

First successful engine run today.  Had some issues on trying to run it on the weekend, and traced it down to a few loose fuel connections.  Still some tuning to be done, but it's getting there.

Heat Shield

Made a heat shield to protect the throttle and mixture cables from the exhaust, as well as keep the fuel servo and firewall cool. Made it out of .022 6061 and used the adhesive backed Zircoflex III over it.
