larry's book said to tighten until they stop, then 2½ turns back. I am unsure what he means by 2½ turns. Is "turn" a full 360 unscrew? if so, then I won't be able to see the tips on the bottom...



yes. easily snap off is right. Luckily, I have some small drill bits, and the adjusters are soft metal. Drilled 3 holes (making a slot for flathead) came out.

If you drilled out the stuck tips that you've probably created a headache for yourself as those holes are tapered. I just had the same thing happen to me last month and in the process of getting the tip out I "coned" out the tunnel side hole slightly which is making adjusting the carbs a pain.
