Couple questions. My rebuild kit shows float settings 1-1/8 & 1-3/4. Manual shows 1-13/64 & 1-1/2. Which is correct? Kit has what appears to be a keeper spring. Where does it go?. Neither manual or my carb has this spring. Lastly a reality check. Power enrichment needle goes underneath the ventury cluster. Right? Thxs for any help. Don F
