You're not providing enough information.

Have things "been great" with carb tops and bodies for the past 2 years or have they always been a problem? If so, what is the problem? You didn't provide any detail. Have you successfully done these parts before?

You should get the results you desire (whatever they are) with the yellow chromate concentrate that you bought from Caswell.

You will NOT get a good chromate if your plate is too thin, which is why I want to know if you've been successful with these in the past. I'm guessing that you've been doing smaller parts all this time and you're not using enough anode and a large enough power supply for the carb bits. You'll need AT LEAST a 10 amp rectifier to get those bits plated properly.
