ive read a couple of your posts and checked the tech pages.. i am going to attempt to adjust my powervalves.. but i have a couple questions i know you guys know the answers.. thanks again for the help... first when i start sled and run rpms down to 900 to open valves , do i shut it off after getting rpms down, or leave it running??? and next is when adjusting these using 2.5 mm wrench for spacer is it the two housings that are being spaced??? thanks again for your help..
 
Yes shut the engine off and it is the 2 housings that are being spaced if i get that part right. Like in the tech section after you shut it down mark the servo motor and the housing so if things move you can line them back up. CCC
