78 Liquifire carb question

[bkopischke]

If I leave my 78 Liquifire 440 set for a couple days, one clyinder fills with gas, I have cleaned the carbs twice, my guess is there is a problem with the inlet needle and seat, I was going to order new one's at Dennis Kirk but there is a number of differant options, which is the correct inlet needle and seat to use on a 78, 440 Liquifire? is it the same for a 76 or 77 440 Liquifire? also last year my 76 Liquifire 440 temp would go up and down alot so I was going to replace the thermastat, where can I get a thermastat? what temp should the thermastat be?
Thanks Blaine
