Hey guys, I think I figured out what it is. I can't start without using starter fluid, and it runs after started. When I hit the gas, the engine takes a little time to ramp up, much longer than before. This leads me to believe it's the acceleration pump.

When I hit the accelerator, there should be a little gas coming out of one or two of those little tubes that stick into the barrels.

I took a picture but I can't figrue out how to post pics. With the top off the carb, gas comes out of a hole in the carb, towards the passenger side, and it looks like it should end up going down the little tube into the passenger barrel of the carb ,but it seems that the little tube is clogged because nothing goes thorugh it. I tried sticking some thin-gauge wire in it, and it won't go through. Should I drill it out? I have some tiny carbide drill bits.
