Hey there. I had posted a question a few days ago about differentiating between a 920 and an 830. Only got one reply and it was a guess, but I don't know how to use this site very well yet, so it may have never been seen. Anyway, I acquired the saw and measured the bore with a rolled up piece of newspaper. Looks like right at 2 1/8 with my precision instrument, so that would mean 920?
The interesting part is that, as I was taking off the 24" bar, it seemed the sprocket was rather large. Turns out it has 9 teeth/pins/whatever you want to call them. I thought 8 was about as big as one would want to go on an 80-something cc saw with a shorter bar. Were the 920s just that torqy that you could use a 9 pin with a 24" bar?
Also, I'm planning on using it but it's been sitting for many years. It's in good shape, starts and idles nicley. but I'm wondering if there's anything specific to these that I should check/replace before running it hard. I've heard parts are harder to come by so I'd like to avoid breaking something right off the bat. Thanks!
