Adjusted the chinese 20" bar... New oil hole and enlarged the slot from 8.2 to 9.2mm.
The cheap .325" 76DL chain, I have lengthed and riveted to make 78DL. Now I noticed I'd have an odd number of cutters, does it matter if I have two sequential lefts or rights? I was thinking I should cut it off and have a skip.
Spot the mistake
I thought, ah I could cut the backwards cutter off, then noticed the drive links also a problem.. To save time I started again and got it correct way around and didnt cut off the double cutter.
Rivet punch worked ok but couldnt get it as flat as standard ones.
Lastly I discovered why cheap .325 bars shouldnt be used with a g372xp! The bar is slightly narrower at the mount which means the chain can rub or jam on the casing and the shim plate. Well too much effort spent to abandon. I lightly filed the case edges to a slight chamfer and cut off the offending protrusion of the shim plate. Not ideal but it now moves freely and dont think it will cause any notable problems.
