<div dir="ltr"><p>I've completly rebuilt a YS 140DZ but I can't get the pump to work.<br>I've torn this thing down so many times I could rebuild it in my sleep but there are a few questions I need to ask about the pump assembly.</p>
<div>Which pump push rod should be longer, the upper or lower?<br>How should the pump plunger be installed? Open end up (towards engine head) or down.<br>It appears that the pump gasket openings are small and may inhibit the pump valve operation. Is this a concern?</div>
<div> </div>
<div>Any help would be appreciated.</div>
