I have been working on my restoration for.....well, longer than i had planned. The engine was running fine when i started and i am ready to hook all of the "stuff" back up and get it going again. The gas tank was drained several years ago and has been sitting dry since. Are there any particular dos or don'ts prior to refilling with fuel? As best as i can see, it looks clean inside with no silt or residue. Comments appreciated.
