I tried somany different things to clean it,as I recall gas worked about the best, acetone worked good but evapration so fast it did not seem feaseabe. I thought for sure wd40 would do it....not much at all if any thing. that engine case now has over 80000 miles, going strong at around 3x the oe horsepower. and much more fun.
With 3x original horsepower, even a Neon might be fun. Borderline at best.
