So if your system isn't already clean, the dissolved debris can make it up to the filter, or into the carbys and the engine.... stopping or slowing the prop.... So you have to make sure the whole system is clean before switching over to E10 and eagle-eye the fuel filter on pre/post flight for a while after you switch. I use a large clear paper fuel filter (no, I won't participate in the fuel filter thread again ;)), rather than the recommended small ones with the rock-like or screen elements. This way, the extra size and filter area gives me a fighting chance to catch any clogging on pre and post flight before it actually plugs up and kills the engine. The little filters clog in a NYC second, but the big ones take a while and hopefully you arrive at your destination before it plugs completely up.....

The motor-has sat for awhile; okay a long while. It was suppose to-have had bearings-and piston rings replaced but everything else was within sp ec.-I-noticed when I hand propped the engine just for oil purging that I had a little drag at one point but could not figure it out. Now two engin es run later with the first for-a very short time to check everything and then a run for 10 minutes.-Today I almost could not-turn the-prop by hand because-of an intake valve-was stuck or it just would-hardly mo ve. I-removed the air intake to the offending valve and sprayed everythin g in my garage to loosen it up. Finally it works some what free.
