77Adam77 Posted March 9, 2015 Report Share Posted March 9, 2015 i have my eye on a reman hitachi carb that fits a 79 620. my haynes say there is some differances from 77-79 and earlier than 77 models, but i was mainly wondering if i could slap this 79 one onto my 77 without having to change anything...hooking up all my smog stuff btw. any connections or vacuum ports on the 79 that would need to be modded to work on my 77? thanks in advance guys. 77 620 Quote Link to comment
datzenmike Posted March 9, 2015 Report Share Posted March 9, 2015 Close enough to work. Engine is identical. If anything it's a small emissions difference. Quote Link to comment
