David,

if it is the factory seal, it must be drilled out. it is permanently sealed 
with a metal slug. if it is the original slug, i would leave it alone 
because it should never need adjusting for the life of the vehicle unless it 
has been tampered with, which would be evident if it was NOT the factory 
slug. if you are having rough idle or acceleration, the problem probably 
lies elsewhere and getting the CO adjusted is only going to be a bandaid for 
the main problem which will remain unsolved. replace all vacuum lines and 
T-intersections, check vacuum solenoids for proper operation, make sure your 
fuel system is ok with proper fuel pressures, change your fuel filter if you 
haven't in the last 15K miles, etc etc. unless i was POSITIVE that the CO 
was improper because of improper adjustments (however unlikely) i would leave 
that slug well enough alone!!
