So i started working on the carb i pulled from my garaged 7 today. I got about 1/2 way through tearing it down to wash the accumulated **** off it, and managed to round off a screw for a bracket. of course, this screw prevents me from removing the air horn. so now its back together and converted to mech. secondaries, pending an ap modification. this is a bone stock carb, and i have to wait till spring to try this stuff out, so that sucks.

anyways, i've sprayed the screw with pb and wd40, does anyone have any other suggestions? i don't want to have to grind the damn thing off since i don't have good luck w/ screw extractors either. i'm gonna let it sit in a pool of pb for a few days.

i usually use a pain of vice grips when that happens. if you got enough room to grab. they work great.

A nice drill bit works great too.

You can screw around (heh) trying to remove it this way or that, or you can drill the head off and forget about it.

I've had good luck using an impact driver. If it's completely rounded off you might need to file a slot in the head and use a straight bit in the impact driver.

Old wisdom passed on to me was to go and find a reverse drill bit. It drills in counter-clockwise and will either grab and unscrew the bolt as it digs in or, worst case, you'll end up drilling it out anyway.

I had good luck with an impact screwdriver too.

You could use a craftsman or mastercraft screw out. Its intended for exactly what your dealing with.

if the bracket was not held by any other screws you can tap the bracket with a hammer in the direction to loosen the screw....it only has to move a little then usually the screw comes right out.

easiest way is us a dremel with a small cutting wheel and put a semi deep slice in it then try a flat head driver to remove it.

yeah i tried hitting the bracket, but that did nothing. since there is another screw about 1/2 inch from the stripped one, i think i'll just grind the bastard off, the air horn should still seal properly, right? thanks for all the help guys! btw i did the same thing the bottom strap bolt for the air pump, and the screw-outs didn't do ****.

I didn't like the kit I got from VB...it had fibre washers instead of metal and wasn't complete. I ended up trashing it and buying one from PartsAmerica.

The one from autozone has metal washers and checkballs.

I have a tool that accecpts different screwdriver bits. Philips, flat or what ever you have that fits. Ya rotate the directional part one way for R.H. & the opposite way for L.H. Within, it has a cam ratchet. Ya insert the bit end into a screw & whack the opposite end with a hammer & the screw to date has always came loose. Next time in the garage I will need to look & see if the Phillips bit tools are small enough to fit in the carb Phillips screws on a secondary carb. The primary carb has been changed to Allen head screws.

When completing your carb job ya might think about replacing the screw driver screws with Allen head screws.

Have Fun ; )
