I bought my silverline a couple months back and it came with a tune up kit so I replaced the spark plugs but when I did that I noticed there was alot of rust in the wells. I was just wondering if anyone knows how I can remove the rust? Can I leave the plugs in and spray it with some sort of rust remover without it hurting anything? They are pratically vertical positioned plugs so I know the rust accumulated because of water puddling. Any suggestions?
