Besides the problem with my choke, I have a serious power lag going up hills. I am moving from VA to Washington, and going over some of the mountain passes I'll be strugeling to do even 40 mph. Before I left VA I replacer the heads, pu a new q-jet carb on, and punched out the cat and put a new muffler on. I'm not sure if the q-jet is tuned right, but the parts house I got it from said that it came pre-tuned for a 305. Any sujgestions would be greatly appreciated.
