Hesistation at WOT?

[RustBuket]

Hi, I've got a 1977 Nova that I'm trying to make run right so we can use it for a dune buggy project. However, when you try to go WOT from a standstill, it wants to bog out. It doesn't stall usually but hesitates and then runs good from then on up to the upper RPM. Is this an over fueling issue? Under fueling? I'm really no expert so I was going to ask what sorts of things I should look for to fix.
Oh yeah, its 2-barrel 305.

I'm assuming its carburated, more then likely it's the accelarator pump, probably just a small crack or pin hole in it.

Hopefully it's just a defective accl. pump like uncle matty said otherwise welcome to carb tuning world where one symptom can indicate either a rich OR lean condition. yippie. P.S., gettin chilly yet? Cary, ex Winnipegger.

Hope you don't plan on jumping that Nova as a dune buggy project . It has NO frame at all , its unibody with a front subframe , and rear leafs .

You need subframe connectors and a cage

As for that carb , someone saw fit to make the book and pics free

Yeah we don't plan on jumping it till we get it tubed up a bit nicer. She'd be pretty wobbly...or it would just fold in half....lol.
So if its a bad accelerator pump, is it injecting too much or too little? I'm going to go with more common = too little....

Take the air cleaner off. With the engine off, work the throttle linkage, while looking down into the carb. Do you see fuel squirting? If not definately bad accel pump. If you only see a little, bad accel pump. Should be squirting out in a fan shaped pattern, at least an inch. The spray won't last long, kinda like a water pistol. Try it 3 or 4 times to get an average. Has the car been sitting long, could be gunked up orifices blocking the fuel from the accel pump. Same symptoms, to me the same cure, rebuild the carb.

Alright thanks for all the help guys. I'll see what I can do.
