With shipping it comes out to be £25 which is about $33, so I don't know if it's worth it or not. There is one on ebay for $40 not including shipping so if I end up buying one Leon's would be the best bet. I have access to a lathe and limited machining skills so I was thinking on machining a new cup from aluminium but making a plastic insert from nylon or similar that presses into the cup and is replaceable, plastic would probably wear out quicker than aluminium but you just put a new insert ring in and you're good to go again. Obviously it would have to be a pretty tight press fit or it would turn in the cup. Some older stihls with the fairbanks morse style starter were like that, but they had notches in the cup which locked the ring in place.I have had good luck with leons. I just bought the nos oregon sprocket system from him for my big saws. And it was alot cheaper than ebay. Keep us posted on your saw, i would like to see a video of it running.
Before I run the saw anymore I want to inspect the bottom end properly, seals bearings etc and try to eliminate or at least reduce the play in the crankshaft rod bearing because I don't want it causing any damage to anything. You can hear slight rod knock when it's idling, and it's 90% in the rod bearing on the crank side, the other rod bearing seems tight.
I came across an IPL for a super 770 on this thread, and found the needle rollers I need are part number 60582A but cant seem to find any for sale. There's various sized loose roller needles for sale on ebay, so when I take the bearing cap off I'll measure the diameter and length of the rollers and see if I can find some that are the right size.
