Should you use the sea foam right after rebuilding the carbs/replacining all fuel lines or after you have run the motor for a while?<br />And can a slight difference in replacement fuel line size make a difference in how it runs?
That will work good - the limit in the fuel line is the connections - where you put the hose onto the metal or plastic conjunctions. But it is generally not a good idea to downsize.<br /><br />-M-
NO, should not make any difference. If you put anything other than OEM, keep a close watch on it as they sometimes create problems because the check valve do not work properly.
