hesitation in new holley

Hello friends,
My question is about a new holley 600 I recently purchased. It was working fine when it began gushing fuel from somewhere. I had a friend look at it and he found some junk that had gotten inside and said that it was fixed. Ever since then, the carb hasn't worked as well as before. For one, the auto choke dosen't always come on and it is still cold here. Also it is sometimes hard to start and the main thing is that there is a flat spot or a hesitation when I accelerate. How can I fix this?

Separate the issues....

Can you adjust the choke housing or linkage so it operates??

Do you have a Holley service manual or guidebook....?? If not, and you want to work on one, I would suggest reading'd be amazed how easy they are to work on when you see everything there in front of you in black and white...

Hesitation might be accelerator pump or possibly a low float level (he might have lowered your floats to stem the tide, so to speak..*G*

What happens if you pump the gas twice before cranking when cold starting?
