Could be a weak fuel pump or plugged fuel filter.
Intake manifold air leak or you need to put some fuel injector cleaner in. Did you gap your plugs correctly?
The problem might be your fuel filter. I know first hand that when mine collapsed it did the same thing. Also might check the throttle control fuse and cable.
there are several sensors and mabe junk in your gas tank
it is the carb. my uncles did the same thing. you need to have them cleaned and have them put in sync

Cuts that work well for fine hair are either longer cuts with long layers to add volume or short, smooth bobs and even pixies. Fine hair should not be allowed to grow too long or it gets weighted down, it should be kept no more than an inch or two past the shoulder.
