Will this carb fit my pulse??

would it bolt straight on or will i need an adapter?

and i was thinking 105 main jet which im running on stock carb at the moment.. i have no idea what pilot is as its been worn down on the head of the jet :/

any recommendations on jet sizes?/ how to fit the carb..

This is the one i was looking at same make as stock one i have at the moment but 30mm.
