Ok,, finally pulled #2 engine and replaced the linkage. When I had the engine off and nacell's open I decided to make another round of tuning all the engines. So I reset the low speed needles on the saito's. Then tuned the top ends. Much better idle. The .30's will idle around 3000 easily and given the weight of the plane 22#'s it won't move in grass. The warning is when idle this slow you have to land under power. This is too slow an idle to plan a final approach and flare. It will drop out of the sky like a stone if you try to flare. So the plane is cleaned up, hopefully I find a location to fly. Temps here 95 humidity 100% heat index of 110. Not really good to spend multi-engine time tuning in the heat. Now send some cooler weather down south.. Jim
