I was going to start a new thread but the first post says thie thread was left open for questions.
Question about steps 15 - 18, when is this needed? How often should this be taken apart and cleaned? What kind of oil should be used on the o-rings (normal paintball oil or grease?)
Question about 19 - 21, what is the best way to take the pump arm off? Does the length of that rod have to be measured like the timing rod?
