After talking to some of the folks in my EAA chapter about my high #3 EGT issue, they said that is indicative of unburnt fuel burning in the exhaust. Made complete sense and I didn't even think of that. What could be causing that? Well maybe a lead fouled mag plug. So I yanked out the bottom plug on the #3 cylinder and inspected it. It looks dark, but the electrode looked fine. I did use a dental pick to clean it out and rechecked the gap. It all looked fine.


I re-annealed the washer by heating it up with a blow torch and letting it cool.


I did a run-up and the engine behaved perfectly. I also re-tightened the clamps on the intake tubes. I did see a lot of cracks on them. I might just bite it and buy a new set. This engine was sitting for some time and the rubber is a little dry. I re-cowled her after the runup and realized there was still a little light left in the night. I love summer. Light until 9pm.


Pic of the sunset takeoff while climbing out on the upwind leg. Calm beautiful night. I also nailed all my landings. What a way to end the day. I love this airplane.
