The oil pump on my sp125 does pump oil with bar off but will not push enough to make it to the bar. Bar oil hole is fine. Manual oiler works great. I have replaced the oil pump piston and good cleaning completed. Diag is the oil pump piston cylinder is worn and blow by is causing weak oil pump pressure / oil push. I am looking for NOS oil pump or any advise to help with this problem. Thank you.
