A while ago I bought a whole box (>20) tune up kits from a marina that went under. The main reason I bought them was to keep what I needed (about 9 kits) that he wouldn't sell separate. Anyhow, now I need help getting the applications for what is left. I need help with Sierra, Preferred, Presto, and Chicago parts. Most are for I/O's from the 80's and later. Please let me know if you can help. I plan on getting rid of the extras, so maybe you can even save yourself some $$$.
