RE: Bubbles in fuel line
Kimhoff,
There is a thread here on breaking in and tuning engines. Do searches on these words and I'm sure you'll find what you're looking for. The best thing to do at this point is to find someone near you who is experienced to assist you. You're going to get a LOT of advice here that may be a bit hard to decipher for a newby.
Good Luck and Welcome to the Addiciton!
