And if you do want to sync, check around the net, you can build a
homemade sync tool and do it yourself very cheaply....But for the most
part a simple bench sync will put you in the ballpark.
For the most part, as the boys said, not an overly long job, use
patience and work carefully and you'll be fine.
My carbs took longer than most (only a pair) but they had sat for 7
years with gas in the bowls (took about a week soak in cleaner to get
the float needles free)
