I have a dwell issue (maybe) with my nephews PMR he got used. Stock dwell says 25 in manual for PMR. But when dwell is at 25 I can't turn the reg up enough to chrono 280 without it leaking from inside the frame. Replaced all new orings on bolt assembly already. So I went to 30, a little better until 35 to get 280-290. Is this normal or is something wrong? I have not opened the frame yet...
Finally had time today. I Started dwell at 20 and reg out each time. Same thing, it did not smoothen out to 280-290 until 35. Actally shoots more consistent at 36! Very strange...anything before 33 it just get a tiny burst of air and the both barely moves turning the reg up to the point it starts leaking out of the frame.
Plus I think the eyes are broken. I can't get it to sense a ball even swapping boards.
The gun is actually wrapped up now under my nephews tree now. I will try a new batt after Christmas. I think he can go without eyes for now since he doesn't shoot to fast right until I find him another set. You know I didn't think to try another battery! Will do!
The guy selling it said it was an 09 so I was basing the the dwell settings of 25 off of the PMR manual online. I'll snap a pic next time as well.
