Can anyone tell me anything about this bar. It was on the Jonnie 630 Super gramps left me that I’m rebuilding. The chain is gone. I ran google on the numbers but can’t find much.
Thats about a 62cc saw, with a 20" bar it should take about 72 links of 3/8 or 375, with a .058 bar groove, which is what the bottom number seems to indicate. A pro shop could tell you what you need.
