I went through all kinds of issues not to long ago. Turned out to be a few problems. Cracked fuel line, fileter up side down (can style) and a weak electric pump. On this adventure I found a CD put out by Holley that give tons of info on how to tune or rebuild your carb. It was money well spen and I learned a ton!! I highly recommend it. Also CHP put out a really good article this month that covers Carb problems. It's a good read, you should check it out.



Good luck!
