I really think you need to do a systematic fix-up/ tune-up on your car. Valve adjustment, spark plugs points and timing, then carb adjustment. In that order! No one seems to have mentioned to you that changing to a two barrel is not bold it off bolt it on. You must change the intake manifold, will probably find the exhaust manifold is cracked and needs replaced, need to figure out the linkage to operate it, figure out and set-up a choke for it. After all that you have to find, go thru and tune the carb. You WILL have at least $500 in it by the time your done. Makes much much more $ense to get what you’ve got performing properly first, then upgrade as you choose.
Also, try to commit to doing it yourself, you’ll learn a lot and know where to start when the next thing comes along!
