My guess is that there is something else causing your engine to not run well at that gap. .6mm/.024" is the gap I've found that covers a wide range of operating conditions. The Pro stator output gives a good pulse at that gap (earlier engines with the MotoPlat seems to be better with a .020" gap). I'd check the plug cap, which gets a lot of tugging at and sometimes the wire comes loose. Also check the connections and grounds. What exactly do you mean when you say "dosent run well on this setting"? What gap are you using and how does the run at specific throttle settings and load? Maybe we can diagnose where the first, best place to look for the cause is. Jon
