[MUTT]

After pawing thru a factory manual & another Superhawk book, ill be damned if I can find the valve lash- cb77. AND, like the other fellow- are thgose two stubs under the inlet ports the crankcase breathers, and indeed there is no, um, "balance tube" betyween the carbs ....Mutt

Valve lash should be seta .004inch intake &amp; exhaust.<br />No there is not a &quot;balance tube&quot; on the PW-26mm carbs<br />georGe
