After I run my motors,I do the flush,but I live in Sonoma Co.Hot days,cool nights.What's your take on this? Should I leave the cover off it when I put it in the garage,and let it air out? I was thinking about taping a sack of silica gel to the hood to absorb the moisture.Is this a good idea? I don't want to leave my motor compleaty uncovered.I do woodworking in my shop,and I don't want sawdust in ther either.To keep the cover on,or off,after a run,that is my question.
