carb list 4777-2, block 11166. Missing holes on passenger side. (see attached photo) These passages link the high speed air bleed in main body to the main jet circuit in the block.
Before I drill 0.025"...
Should these holes be:
1. blocked both sides
2. clear on driver side only (as is: counterintuitive.)
3. clear both sides.
If you have any 4150 2nd metering blocks in your parts bin, please take a look!
If you know from experience, even better.
Thanks in advance!
