Checked and rechecked stuff today. Looks all good. BUT. I may have found my issue, except I'm not sure how to fix or what it is. I looked at everything and I mean everything and I'm just stumped...
So, how do you like your chains tensioned? Like this? :msp_biggrin:

So the thing is, this is the same tensioned bar, just 3-4 links apart. Does this every 3-4 links. Bar is straight, crank has no wobble, rim sprocket looks great, bar nose sprocket seems good, I've looked at it every way from Sunday with calipers and I see nothing wrong, nothing out of line, nothing with the rim making any movement up, down, sideways, nothing. But I think whatever it is may be my issue. I like to tension like the first picture, if I do that, then I suspect it gets way tight (so overtightened chain may be the actual issue) as it travels the 3-4 links throughout the bar.
The thing is, you don't notice it when tensioning under normal circumstances. By that I mean after getting it just right, I give it a whirl around the bar. Seems pretty normal at that point. IF I go slow and light, I get these hang up points like something is getting in a bind or hindering the forward progress, for just a split 1/4 inch then it smoothes out and continues onward. Sometimes the cycle is not as persistent around the bar, but may only be due to the forward progress. Again, not sure what it is. Don't think it's normal in any way and is likely at least a contributing factor in my issue. Thanks for input.
Finally, how do you get your pics to show up in the thread without having to open them. I know this site has changed, and I'm an IT guy and used to explain how to post pics in this forum, but I missing how to do that too. Other than that, I like the new look to the site. Thanks.
I had a similar problem with a 180c. When pulling the chain to check tension the chain would hang up every now and then. But that is a completely different kind of setup. Spur vs. rim. I also had a chain SPARKING issue with a 036. If I would jolt the saw good in my hands while running it the chain would throw a decent amount of sparks. That actually turned out to be the sprocket needle bearing. What I am saying is you might want to pop off the rim sprocket drum/needle bearing and make sure that is all good.
I like my chains tensioned like the first pic.
