1987 150 carb jet plugs broke off in bowl. best way to remove??

[SparkieBoat]

Ok guys , I have broken off 1 plug in each of my 3 carb bowls. they are brass and I assume I could drill and tap, but I do not want to damage the threads because these bowls are NLA. Before I got drilling, I figured I would check with the pros and make sure I am going in the right direction.

If you do have to drill get a set of left hand drill bits. Many times whatever you are trying to get out winds up screwing right out due to the heat and vibrations from drilling. Harbor freight carries a set that is cheap but suprisingly good quality. http://www.harborfreight.com/13-piece-left-hand-drill-bit-set-95146.html

I drilled them out by starting with a 1/8 bit and worked up. I used left hand bits up to 1/4. That was the largest LH bit I had. Then I used a 5/16 bit, then I used a tap and cleaned the brass out of the threads...it worked real well...one of the plugs actually came out while drilling with the left hand bits. so all is well. Thanks for the help.
