(get below the thinnest part of the cyl fins) cyl #2 is next hottest, air is again stopped at the thin fins, this time by the oil cooler box. cut a hole in the oil cooler box so air can flow around the cyl. starter adapter slipped on hot starts and was replaced under warrantee. oil vernatherm broke and was replaced under warrantee. rudder cable to push rod assembly became sloppy and was removed and rebuilt with more parallel surfaces decreasing 90^o offset free play. rob logan bad modifications: center tank vent issues gap everything before paint... lots of gap, paint is thick!!! com antenna switches impost an unacceptable line loss remote oil filter on engine shakes too much. cowl ram air blows / cools #4 and I'm not convinced the net effect was worth the effort. oil air separator into oil holder, overboard or into cyl head, remains a question. two 100 watt landing lights need big wires and +20amp breaker. my electoral design overloaded the "second" alt, so I moved all lights to the primary alt. the new hyd pump (gear up in 3sec rather than 6sec) is very cool, but required larger relays & wire. (load is really 35 amps, even tough its rated at 70 amps @12v) --- hot start is old news to most of you, but this is the process I learned from an ovation driver and works well in the legacy: cold: push thr, prop, and mixture full forward.. high boost for 5sec pull thr full back and then forward 1/4" start (with cross tie) hot: push prop, and mixture full forward.. pull thr full back and then forward 1/4" start (while slowly advancing the thr) as soon as it fires: low boost work the thr back to idle low boost off if failed to start, prime like cold, but only 3 sec after 4 of above: pull thr and mixture full back high boost for 30+ seconds goto hot start process. -- Utopian Maturity: Eternity, Liberty, Equality now Fraternity & Altruism.
