If there is a hole on the right side of the throat it was a butterfly choke carb, same carb they based the Raptor carb off of except they deleted the choke and breather vent on the raptors, well at least they did on the later gen raptors... If you look at the bottom of the carb the area where the hole is it should be thicker for the bolt to thread into.. It will not go into the tank.. It looks like hone marks on the throat? if so pull the jet out and make sure the carb was not modified for alcohol, if it was your going to have to use alky or find a different carb..
