Today I put the lp chain on the 361 and cut one board. The chain loosened often and I had to pause alot to keep it from snapping again. The board was loaded with grooves.
I took it to the shop and took off the chain cover and moved the chain by hand. There is some resistance of the chain in the 3/8 7t sprocket. It fits but doesn't fit perfectly. This is the used sprocket on my 361 not the new one on the 660 (non-compatible). It's the new one that caused the wear in your photo Bob but i'm sure its similar to this one. All I can come up with is the chain doesn't like my 3/8 7t sprockets, new or used.
The bar ideas mentioned above are good but its a stihl 3003 000 8921 20" with a fixed tip and decent rails. On the side it says 3/8 .50. All my other chains run fine with this combo.
Am I the only one that has resistance with the LP chain on this size sprocket?
I can't come up with anything else and baileys has the regular rip chain on backorder so my project is relying on my backup 20" rip chain and the 3 .404 36" that I have (which are a bit large for 2x8's)
I know this is a long post and if you are still reading this I thank you for all your help. I'm running out of options with this chain.
