My 54 235 with Model B hand choke, Rochester starts fine when cold, but when hot it needs starting fluid, or full choke. Dwell set at 32 degrees, timing on the mark, idle mixture set at best vaccum, idle speed at 600. No headers, only mod is 12 volt alternator. Has been setting for seven years, had gas tank flushed and sealed, rebuilt carb. Could not replace pump plunger because pump in kit was different. Used a Walker 15157 kit. Any ideas?
