Hey! Just crusing at slight throttle it runs awesome, as soon as i get into the trottle a little bit I get a slight bucking, surge. When I get on the throttle a little more it goes away, im thinking maybee running a little lean part throttle? Think I should richen it up?

Check for vacuum leaks first.

stop holding so tight on her ears

HA HA thanks guys, wouldent a vac leak be evident when i stomp on the gas, im gonna check anyway tho, thanks!

Check to be sure you get fuel flow immediately from the accelerator squirters. Might help changing to the bigger shot hole in the linkage, if it isn't already. Not necessarily for a bigger pump squirt, but because it will place the pump piston at a different place in the bore. This is what might help the pump to give a quicker delivery.

Could be the timing- if you're using a vacuum advance can, the decrease in vacuum caused by the acceleration will cause the timing to drop. Possibly adding some more total timing and decreasing the vacuum advance a like amount might help.

my first thought is to try a stiffer spring on the metering rods, might be lean until the vacuum goes down enough to hit enrichment mode.

I tried the springs on the meetering rods a week ago, i went to a smaller rod tonight and made a big difference, im gonna go a little more and it sould take care of all of it, at least its an edelbrock!

maybe increase the accelerator pump stroke?

right ill try that out
