With regard to the carb, I don't think they're bad per say. The real weakness is their reliance on vacuum for the solenoids. The stock vacuum hose setup is a rat's nest and vulnerable to leaks from every angle. Provided there aren't any vacuum leaks, the carbs perform relatively well though.
I put a Webber 32/36 DGEV on my '79 and eliminated all the vacuum lines. Pretty staight forward conversion. The only thing really worth mentioning is the coolant port that sits right under the carb base on the stock manifold. You'll have to block this off somehow. In my case, I threaded it with a 3/8" NPT tap and screwed in a corresponding 1" long grub screw coated in permatex. I also had to fiddle with the jetting of the Webber to get it dialed in right and advance the timing about 2* from stock. Runs like a champ now. Oops, I mean runs like a BRAT now!!!
