Unfortunately, I don't recall which one it was. I do know that Andrew the Parts Guy had to get the M110 PAPER book from under the counter to figure it out. The parts book lists "Screw Plug xx MM" and you want the one where xx is the size of those plugs on the left side of the intake.

But I will look at the book and my receipts tonight and see if I can be a bit more definite.

The problem with plugging the pipe is that you need a metric pipe and metric threaded plug - not a Home Despot item. Besides, with all the practice you've had, you can have that carb off and on in 10 minutes. You need to check the puddling in the intake anyway. :-)
