I had a good feeling last night when I finished all of the engine work on the KB install; all I have left is adding the chip and BAP. Sometime during the night my eyes suddenly openned realizing I had not cleaned the butterflies on the IMRC! Although they were not gummy, I had planned to clean them up with some carburator cleaner before re-installing them. Should I tear everything back down and clean them or is it not that big of an issue for now?
