After numerous questions posted and many, many, many hours of soaking/scrubbing/assembly/searching/etc my carb upgrade is almost ready so I thought I would offer a sneak preview and ask one more question.<br /><br />Here's the beast in question:<br /><br />
<br /><br />This thing looks huge and mean just sitting on my workbench. Anxious to find out how my tweaked 302 likes it!<br /><br />The carb is a Holley 6576 from a 1972 Mercruiser 255hp/351 IB.Fresh rebuild kit with new Electric choke conversion. 600CFM, Vacuum secondaries<br /><br />Factory 1" spacer block<br /><br />Weiand 8011 Aluminum dual-plenum intake (freshwater only)<br /><br />Yup, I painted it silver, mainly because I had it left over and the cleaning process stripped much of the bronze. <br /><br />Finding a Merc factory throttle bracket for a Squarebore is a pain.<br /><br /><br />Now for my question. There is a spring around the throttle shaft, presumably to close the butterflies if the cable comes off I'm guessing? It wasn't set properly when I got the carb, and I can't figure out how to get it set right. Anyone have a diagram of how to set this spring?
