the carbs as standard will probably be piss lean on a standard car engine as the car wont flow enough air to draw enough fuel with the standad bike jets, try dropping the needle or raising the needle on the slide, just take the top off the carbs, then pull the big spring then slide out, then the needle should be on a circlip, if you lower it you lean it off, and vise versa. will give you an idea if its lean or rich
