If so, what was your experience? 11. Start with your smallest number drill and try pushing it through the restriction located under the alum. plug. Go up one drill size at a time until you find the largest that will go into the restriction. See Fig. F. In my carbs that was a .070" drill. Now take the very next drill size larger, place it in a pin vise (cheap), and drill out the restriction. See Fig. G. Go far enough so that you see the end of the drill in the center vent hole. Put everything back together and drive it again. You may or may not see an improvement. If not, or if its not enough, go through it all again with the next size bigger drill bit. Keep going until the hesitation is fixed. I ended up using a .078" which worked quite well on my duals and on another triple set up. Both were 261 engines. Remember this effects only the off idle under gentile acceleration. It also enriches the idle mixture so that a needle adjustment will be necessary.

I have also seen posts that talk about cutting the length of the spring on the power valve. Has anyone done this? Does it work?

It was a long time ago and on my Packard
First thing was to make sure both carbs were the same in every way
I used some led shot from the fishin' store to cover the hole
It was all pretty easy | | |
