i have a spider MR2 ,and some freind messed with the speed adjuster screw .So plz i want to know if i want to increase the speed i must tighten the screw or losing it ..and what is the maXimum speed that MR2 spider can reach . thx
In a spyder the velocity screw puts tension on the hammer spring. The more tension, the harder the hammer hits the valve stem. The harder the valve stem gets hit, the longer the valve is open to allow air to go through. Hence, more air = more velocity. Also known as dwell..
