Slowly, but Surely

Don't know yet 340. I'm going to look at it this afternoon. A guy at the track showed me the linkage arm that adjusts the secondaries. He said it needs to be "tweaked" to fully engage the secodaries. However I went to QFT's website and they sell different sized rods to increase the progressiveness of the secondaries. What do you think? And will this 750 D.P. be enough? It seems like the motor is begging for more. Thanks for the feedback from everyone.
