Thanks fella's. That pinch really makes it easier to needle.

My Jett came up to 24.8 as soon as i pinched it, brought it down to 22.5 to fly. It's a new engine and I wanted a very rich flight to trim and get some air time on the engine. Flew with a 7x8 wood prop. After 2 runs, the plug still looked like new.

Will run the Nelson's in a couple of days.

Thanks again for the quick responces.
