I would definitely check the carb. I had this same problem, and there were minute amounts of debris that had clogged the passages. I dipped the carb in a bucket of Berryman's carb cleaner, and left it for two days, then blew out all the passages with compressed air. After that, I checked my hot-air manifold up to the carb. You can do this first by letting the car warm up; go for a short ride, and come back and touch HOT!!!!! the small manifold tubes that go up underneath the carb. These MUST be hot as it acts to vaporize the gas and stop carb icing. If they are plugged with carbon, then you need to clean them out, as the carb will act as you say. Use a piece of old clutch cable that is frayed on one end in an electric drill and try and work through the carbon. I had one that was HOPELESSLY plugged up, and without access to an acetylene torch, we had to pour some potent carb cleaner down the tube, then use the clutch cable bit. It took 2 hours, but we finally got through to the other side. Also check that your accelerator pump is giving a squirt of gas down the carb, and that the squirt tube is aimed in the correct position. HTH, Courtney
