My Caddy will be off the road until at least the spring time now, and so it is a good time to start doing a little more in depth work than just fluid changes I have been able to do since I bought it at the end of the Summer. I was thinking maybe I should rebuild the carb on my 1970 SDV w/472. The car runs pretty dang good right now as it is but I wouldn't be surprised if the carb has never been rebuilt in the cars 90,000 mile lifespan. What are the symptoms of a tired carb? I have noticed that when I floor it even when it is warm it almost stalls for a split second, then roars to life, although I suppose it could be the accelerator pump as well? While I have the carb off, would it be a good idea to take off the intake manifold and heads as well and just to a good cleaning of the engine and replacing of the gaskets? How hard is it for someone who has no experience in rebuilding carbs to do so? I do have the factory service manual for my car and a lot of patience and time. How do I get the carb number for the rebuild kit? Is it the same for every carb of that year or is it different for every carb made?
