holy balls! lol. That is a fair amount of preload. Its dependent on which clutch spring, the clutch disc (yellow or white), and when you really get into it flywheel weight (std or lightened) all play a part in how your clutch performs. So I am going to assume you have the standard xray silver clutch spring (black requires less preload, same with the orion square spring). also assuming which clutch disc (yellow is most popular but is optional)

Assuming your using a silver (stock) clutch spring with yellow clutch shoe your gap should be closer to 0.5-0.6mm. On slick tracks I run as low as 0.4, 0.6 is more for larger layouts and / or high bite. So lets say 0.5 gap to start, and about 0.6mm preload. If that doesn't engage, reduce preload to suit. Next to nitro tuning, clutch tuning is often hard to learn by your self. If your running a stiffer than stock spring like the orion, I start with 0.4 gap, and 0.4-0.6 mm clutch spring preload (preload in this reference is the difference between the clutch nut measurement, and the flywheel nut measurement.) so your 9.35 should be mated with a measurement closer to the 9.75-9.95. On a worn spring sometimes I end up with more. But a reasonably new spring shouldn't be that soft.
