HI new to the site have a question I can't find the answer to I got my first Honda a 1981 cb750 I have been building. after getting it alltogether I tried to start it and it would start back fire out of cylinder 3 and die. I have good spark so I assumed the carbs were out of sync but after looking they are at least bench synced. My question is what is the next step in tuning the carbs without being able to get the bike running. other than that I'm not sure where to go next. Any help would be appreciated.
