I ran my IO-360 model B1F for the first time in several months this weekend. The engine won't idle below 1200 rpm or else it quits as if the mixture were pulled. The first two times on the starter, the engine coughed but didn't catch. On the third time it caught but was very rough until the rpms were brought up with added throttle. Previous runs of the engine were much better, with the best being the initial time it was started where it would almost idle at 600 rpm (throttle pulled all the way back). It would also start on the first cough. It seems to have gotten progressively worse. I haven't touched the linkages on the stock injector unit. The engine is a new factory unit. As an aside, I can't raise the power much over 22 inches or I drag the tires! (wings and associated weight not installed) Might this problem be fuel line contamination with particulates? If so, where might they accumulate and how do I clean affected parts? I have an inline filter just under the header tank. Other things to try?
