I am having some trouble getting my carb to work. Engine was running and just did some work on one of the coils. Now I cant get it to start. Engine runs fine if I spray fuel into the carb, and I can see the glass bulb filling up with fuel, but the carb is not spitting any fuel out. I clean the carb and took it all apart and it looks ok, but I don't really know what I am doing with the carb. For some reason gas isn't flowing through it. Can anyone point me in the right direction? What could be going wrong? What should I be looking for? Thanks!
