My Sunrunner 1691198 likes to drop its drive chain. I think I've got the axle correctly aligned and I think the idler is tight enough. The upper sprocket and the idler are both new but I haven't changed the chain itslef yet because somebodyu assembled it with the spring clip in t he master link on t he inside which makes it hard to get at. Any comments on tricks or tips to keep this chain in place?
Same general vein---does anyone have experience with transmission failures? Interior chain failure, or damage to the keys (which are unavailable)?
