Engine emergency caused by clogged fuel filters (John mentioned debris caused by some fuel tank work of some sort?). Saw fuel pressure fluctuations on EM2 and increased EGTs then rpm started falling. After landing, John found the clogged filters & cleaned them out. That procedure called for closing a shutoff valve from the tanks. After cleaning the filters, he forgot to turn the shutoff valves back on, hence the failure to start. He eventually noticed that fuel pressure was super low and that eventually jogged the memory of the shutoff valves. After opening them, the engine started immediately. The RPM anomaly is still a mystery & I didn't think to ask him if that was back to normal. I'm sure we will hear more later. I'm kind of amazed that the engine still had good compression after 50 gallons of fuel with no oil added was used. Just random thoughts: I'm thinking I should cut back on the amount of oil I add. I'm still accumulating 2 stroke in the crankcase when using 3/4 oz per gallon of gas. Think I'll go to 1/2 oz / gal. on Renesis. Peripheral exhaust port 13Bs need more oil than Renesis but 1 oz/gal is probably overkill.
