Hi, i use the same kameari on my L 24 race car, in the papers its says 35-38 degrees @ 4000 rpm, and thats the Way to adjust it, have a ignition gun that Can adjust the degrees, and rew up to 4000rpm and set the ignition to 35- 38 degrees, but have in mind that it is a very High settings, and depending on the fuel you have acess to it Can be to High, i set my car to 32-34 degrees, running on Shell V power (Europe Denmark), i guess you have a diffrent Ron scale in the US. Lars.
