carb cleaner

years ago when I was actively building these old cars, I used the pail of NASTY carb cleaner. I have mechanic ( tractor and sometime car) mechanic. he cleans carbs with the good brand of spray carb cleaner. wondering if this is adequate.
working on 63 dart slant, with the 1920 , rod working vintage. I just put in engine and got it to fire for just a secomd . shut if off as I don't have throttle rod for it and I want to add mechanical oil pressure switch too, the old carb ( someone sent me), its plenty nasty lookin, the accelerator pumps works, and it started leaking at bowl. looks to be good just needs cleaning and kit.
I hate that stinkin carb cleaner. in the pail...... will the good spray stuff be adequate?????????
