suzuki ts50x engine/electrical fault

[Ajoggy]

I have a suzuki ts50x and all of a sudden it started playing up, coughing spluttering and dieing as soon as you tried to pull away. I have changed the carb, spark plugs, spark plug cap, cleaned out the fuel tank and tap and the air filter as well at the fuse and spark plug coil but still havent had any luck. Any ideas of what the problem could be?

Wrong section, but when i had mine (many years ago) i once kinked the fuel filler vent pipe which meant a vacuum grew in the tank and the bike cut out / wouldnt restart. When you take the fuel tank cap off does it sound like air is being sucked in, and does it run with the filler cap off?

Back to more conventional stuff you have tried:

-Does it spark?
-Is fuel being delivered (is the plug getting wet)?

I have tried all of those things and it still wont run, completly baffled about what it could be. Thanks for the advice tho
