It might be worth opening the drain screw to clear the floatbowl of any old fuel

As Dave says check cambelt is intact also check it hasn't slipped on worn pulleys - do all timing marks line up ?

I only managed to take MT350 carbs off by removing the airbox and battery tray. I found it easier to detach the enrichener cable at the handlebar end. Detaching the two throttle cables by slacking them off is easy enough but make a note of the cable routing before you touch them. I found it useful to put different coloured tape on the cables so that I knew which fitted where. If you're going to remove and refit the carb, I'd renew the cables at the same time. Some owners run with just a single cable and rely on the spring to close the throttle. Old cables dry out and don't move as easily as new ones.

I can't remember from your posts whether you've ever had the bike running ?

Rubber boot split ! Yep that could well be your problem. Wrap gaffa tape around it and see if the engine runs. If your bike was running fine recently , I doubt that it's dirt in the carb , it's unlikely that a piece of your carb rubber has broken off and been sucked in, but anything is possible.

You should be able to cut your old boot off easily enough and a new one will be far more supple so you should be able to get that on without disturbing the carb
