Well thank you Karl...I see what you did now. Here's another idea! try crushing heck out of aspirin, then disolve in acetone, and let dry, THEN add that to the alcohol w/ some H2O2, and see if there are still particles? I haven't used a filter yet but will from now on. I started the other aspirin thread, MPG remedy, to try to give this deal a name, read that yet? Dan adds the H2O2 as a bacterial retarder, reemember gasoline is based on a organic source, crude oil. I'm relying on Dan's decades of experience w/ all this. It's said that acetone is negated by alcohol, but I haven't seen the reverse stated anywhere?
Oh and you wouldn't be the first to be freaked out by the subie's engine bay, the diode blocks look science fiction nobody understands 'em! LOL But actually w/ the weber DGEV, it's a lot less cluttered under there, easier to work on too. Still too many black long things in there, even I have to carefully sort vac. hoses from the heat shrinked diode block wires, nobody ever sees plug wires w/ a separate lead going to plug boots...
Sorry I forget, where do you live, what region, have you been hammered by the fierce cold as so many have? Deep cold sure doesn't help our engines.
BTW, check your email, Karl!
cheers! Tracy G
