    Nabmd, this info helps.  My son replaced the o-ring but we were not sure of an actual starting point for the valve position.  I think we are too open.

    My 13 year old has undertaken this project and has made enough progress to get a short firing sequence.  With all the info everyone here has provided he might be close to his goal of getting it running again.

    It is certainly true joining has its benefits!  Thanks all.
