:confused2: First thanks to Bob/Bubba with all the advice. The 70 Evinrude is back on the boat after the rebuild. And look ma..I did it all myself. minus-boring I got some good advice here. Still gotta hook things up and test it out.....Now I thought I marked the carbs when I pulled them off but some how I got two marked #3. I rebuilt the carbs and synchronized them per the manual. Is there any difference in the carbs or is all ok?
