take the top off the carb (very simple, you will have to unhook the metal rod linkages but apart from that a few screws) and have a look inside.
If the float bowl is full of crap you know you have a problem. Clean it up and then start the engine. You should see a steady trickle of fuel from the idle tubes into the venturi and a steady level of fuel in the float bowls.
If not break out the carb cleanere and try to get those idle tubes cleaned up. You may have to take the carb of and take more of it apart.
Before you put it back together as a minimum check the float levels with a ruler. Carbs are sensitive to this.
When the top is back on you need to look at the accelerator pump and metering needle settings. Go on the Internet and find the instructions.
When it is back up and running check for vacuum leaks all over the manifold area and hoese, your hoses look old and could do with replacement.
Finally adjust the curb idle and idle air screws until it runs smoth. It will not do so if the tubes are clogged, the floats are wrongly set or there are air leaks.
