ok after posting this i went to try to start it again it started and idled fine then i went to give it some gas and it just died and cant get it to start again

you may want to look at the accelerator pump in the carb and you may need to do something with the pilot jet, thats what controls fuel at idle and low throttle

sounds like its sucking air maybe, check the spray some carb cleaner around the intake manifold and see if the motor revs up, if it does, then you have an air leak. its a cheap test and will be quick to eliminate if nothing changes when you spray it.

thanks everyone with all the replies after messing around with it i just put to big of a main jet it was giving to much gas but it running great but thanks again everyone
