coolerow Posted May 11, 2013 Report Share Posted May 11, 2013 Have a single 44 I am currently rebuilding and noticed it has 2 vaccumm ports on the runners and 2 fuel ports(?) on the pump. Could not find sufficient information on these ports, can someone explain. Also can these be blocked and not affect the drivability? I remember my old set of Mikunis not having these. thanks Quote Link to comment
oldskoolvws Posted May 11, 2013 Report Share Posted May 11, 2013 Vacuum gauge tuning, at least the two closest. I think I have a few links somewhere.... I believe they actually sense airflow through each tube. Quote Link to comment
