Hi, thanks joining in with your problem and Welcome to a great forum.
OK, so it cranks, fires and idles, if only for a very short period?
Based on what you stated.... sounds like a fuel delivery issue. This being the case....
1. Has the carbs been rebuilt, to include a good cleaning internally and externally?
2. Is there a nearby external filter that could be clogged?
3. Have you checked the entrance filter to the carb for being clean?
4. How about the fuel pump? Have you checked that it produces a good fuel stream into a bucket?
Most of the time, when a engine starts, idles then dies shortly thereafter, you should suspect fuel delivery. Fuel delivery begins in the tank with the fuel pickup "sock" or screen, you have a line from the tank to the fuel pump, through the fuel pump to the carb and any filters in-between. Could be the diaphram in the pump is bad and not pumping fuel under minimum pressure to the carb? Could be the fuel bowl has sediment and this sediment has has clogged the idle circuit and others. This is why I ask, if the carb has been rebuilt.
Ponder these comments and get back.
