This is the only video that warns about making sure the sprocket engages the oiler gear. Good job. thanks.

Rein's Notes: ;-) 0:43 and 1:53 Lester gets fancy with graphics! We love it! 2:30 Slow motion!!! Cool, dude! Great to really get to see something that usually happens so fast we miss it. Wow - that sprocket was the worst I've ever seen! Talk about letting something go too long! I'm working on a Stihl MS180C given to me by an arborist buddy who got it from another friend. The clutch drum/sprocket bearing was blown out with only about half the bearings still inside and no sign of the cage anywhere. I've replaced the bearing and the saw is running fine, but there are other things associated with that like weak clutch springs (replacements on the way) and some melted plastics underneath. I suspect the saw was run with the chain brake on. No other signs of actual damage - P/C/rings in perfect condition and 175PSI compression. The cylinder is somewhat darker than original color but otherwise it's fine. Touched up the chain and that saw cuts like a beast! As soon as the springs are replaced I'll be able to finish tuning - at least to confirm spec idle and clutch engagement speeds. Lester, can you think of any other reason for the damage I found? I appreciate seeing you set the brake to lock the clutch onto the shaft. I have suspected that would do the job but you're the first person I've seen actually do it. I always test the brake after I get the saw started to confirm function anyhow. I got a new tool! I've had problems with my Tiny Tach from the beginning but haven't been able to afford something better. A couple days ago I discovered a smartphone app called Engine RPM, loaded it onto my phone, read some of the instructions and tested it out. It's tricky to understand at first, but once you get how it works it's great! I checked the speed of my fridge compressor, oil burner, bench grinder and even the speed of a saw being tested on a KZbin channel! It works by sound instead of electrical impulse, so as long as my phone can pick up the sound it'll function. Really great tool that is going to change my game completely because now I don't need a hand to hold a tach up near the spark plug - I can set this down nearby and have a hand for the throttle and another for adjustments. apps.apple.com/us/app/engine-rpm/id340401811

Just a general note, the basic wear and tear on sprockets (it's amazing how many power saws I've noticed come back from a 'full service' still with their old worn sprockets still on them). And why would it matter, if the sprocket is not totally damaged? Well, it's the chain is my understanding doesn't benefit from a uniform tension applied to it. There can be parts of the chain's rotational cycle in which the chain comes under excessive tension, then followed by lack of the same. And it basically results in poorer chain performance, excessive stretching and strain to the chain component itself. And considering that 'good' chain is important, and not cheap to buy, store and sharpen. It's a real pity for the sake of a sprocket replacement once a year, that one is losing a lot in terms of one's chain reliability and performance, because of a lack of attention to the said sprocket maintenance procedure. I discovered a worn sprocket on my 65cc saw a while back, and it annoyed me, as I'd used it as a saw in workshop to mount chain on to, sharpen and test in wood for a while. Before taking off the chain and storing it for use on my other saws. Little did I know, I was doing damage to each chain I re-sharpened, by using it on that saw. It was really Oregon I think, a dedicated chain and bar maker who put emphasis on it for me, in one of their instructions.
