If you have a idle screw for low speed adjustment. Change your pilot jet to a 45. Then close the idles screw. That should give you more bottom end.

Generally go to a bigger carb only if you have a BBK. Without a BBK you are going to loose some intake vacuum and reduce engine performance...no matter what jet you use...

Bigger displacement... more vacuum...bigger carb
