Jet sizing

4781- what? There is 4781, and 4781-1 thru -8.
Standard 4781, stock jetting is 80 jet front and rear, 6.5 power valve f&r, 35 shooter primary, 25 shooter in the rear.
Other list number dashes had other jetting and shooters (25 rear shooter seems awfully small to me).
Later dash numbers had leaner secondary jet, and 31,31 shooters.
