Re: dead cylinder
What makes you so sure you are getting fuel into that cylinder? why do you think its dead?
Re: dead cylinder
My first try would be to swap plug and cable with #4 and see whether the problem moves to #4 then. Easy and effective check.
For compression, turn the engine by hand with a 24mm socket on the right crankshaft side. You should feel four equal compressions during two turns. If one feels considerably weaker, this probably is your problem. Only a tight valve, if you are lucky. If the engine stood for longer, sticking rings might affect this test.
If ignition and compression seem all right after that tests, check the carbs. First try to drain fuel from #1 carb bowl. If you get fuel, remove the the floater bowl to have a look for dirt.
