I recently recieved and autococker( serial number# 89190) from RoBo and need some help with it. I was told it is out of time and have tryed to set it up according to the giude I got at cockertech.com with No luck( But I have never had one before so I am cocker stupid). What it doing is not cocking the gun on its own it will cycle the ram but the cocking rod dosen't go back far enought to catch. If I pull it back manually it will catch . What do I need to adjust to get this working?
