surges after running for awhile

ok, I watched those edelbrock videos the other day. This morn I pulled out one of the idle needles and started the car, it ran well until lunch time. So i just took a air compressor to the idle hole with the needles out as shown in the vid and wow, what an instantaneous change! sounds great now and no stubbles :)

hope it continues that way through tomorrow.
Thanks for the vids dart170 and help FABO!
