Ok the manifold is off so I figured what the heck I'd tweak the ALDA a bit.
1. Their was a black plastic cap over the screw, I broke it and now no cap. What do you guys use to cover it after you adjust it? I'm going to try and get another cap.
2. There seems to be almost like a tin collar around the top, and it seems to hold the plastic cap on. How do you remove this?
3. The scew is stuck, currantly I have some PB Blaster working at it. Any other ways or tricks to break it free?
