How did you guys do it? The manual says to saw a notch in the throttle body, then "use center punch to break plug apart, to uncover idle mixture needle. Remove all loose pieces of plug."

I don't know what musclehead wrote this manual, but my plug didn't break apart. It bent my punch. Then it smoothed out all the rough teeth on my hacksaw, dulled one of my drill bits, snapped another drill bit in half, and in the end I think one of the plugs is further in the hole than when I started.

How the hell do I get this out? And why's it even there in the first place?

 

you cant saw the plug! saw the botom make a V then punch the plug out by the *hole*. Underneat the carb you should see 2 dots on each site, this is where you want to saw.

Gm dont want you to mess with the ajustement heheh.

well... i have not done mine yet, but i saw 1 side alredy :P , did'nt tryed to push it out but, the carb base is soooo soft, be carefull.

good luck, sure it wont look preaty after but, it's the side facing the engine

i'll check if i can make a pic tomorrow.

 

Yeah, the throttle body does seem much softer. How much material can I remove? Can I drill all around the plug? ie, make the hole bigger so it falls out? I sawed like it says in the book, I've hit it but it won't budge.

Sheesh, no wonder everyone just buys Holleys.

EDIT: finally got them out the other day. In case someone else has the same troubles, I used a carbide bur and a lot of patience.
