Reply to "Five Cent Racing's Engine Throttle Hold Tool"

McGruff:  yes.  It eliminates the small difference you’ll get from that “free play” you feel on either side when tightening them up.  

Adjusting them with the engine off idle (I say 2K rpm but 1,500 and up is fine) will put force on both links as you adjust/tighten them and you can sync them closer. 

I increase speed with the tool to the point where the higher side matches the moving snail needle with a reference bar perfectly, then bring up the lower side to perfectly match needle and same reference bar on that side - it’s not going to be very much different, but it will be different when you start.  I have always noticed the engine running smoother after adjustment than if I just static balance them at idle.

Of course, that may just be “Mechanic’s Optimism”, too.  Jus’ sayin’......
