If you are referring to the tuning post by Dayclona, I have that one as well. I returned my timing back to my base setting, I have to run more idle than I want but I have no fear of running too much total timing. I also took the scondary linkage off, disconnected the vacuum lines to the pods and blocked off the supply at the center carb today. Going on Tom's thought of get it running correctly on the center before worrying about the outbaords. I still have the surge but just minor with the outboards out of the picture, I will pull a few plugs tomorrow and see how they are liking the 65 jets. If I can get them to look right I can live with the surge that is left in the end and then I can fix my total advance so I can run more base and bring the idle down. Interesting playing with it but I really wise there was someone in my area more familiar with them than I am, few people around here even know what a carb is much less multiples.
