I would like to use a vacuum gauge but I’m not sure how to hook it up once I buy one. There is an intake port just below the carburetor on my 235. (see the first link below, lower left after the PCV). Should I use this port? http://i4.tinypic.com/10furl5.jpg http://i4.tinypic.com/10fuxz5.jpg What is an optimum reading on a vacuum gauge for the carb mixture? Thanks for your help. Mark | | |
