Please diagnose my KA mixer -- bowl lift not working
Hi, I have a KA Pro model (Pro HD, I think -- I believe it was a Costco model) bowl-lift mixer. I bought it used and it was never in tip-top shape but, while making a large recipe of cake batter recently, the lift mechanism failed on me. Now the lever doesn't work well at all (barely lifts the bowl when empty and won't lift at all without assistance when full) and will not lock into place on its own. With any load in the bowl, I have to push up on the lift arm while turning the lever or the lever just keeps turning and won't actually lift. I also have to get the lever into just exactly the right place (usually after multiple tries) or the lift arm won't stay in place at all.
Is this fixable? I am guessing it is but how do I do that and how much will it cost me? I am wanting to just sell this mixer since I don't love it anyway but I won't get any money for it as is and don't want to try selling without fixing it properly, either.
Thanks in advance for any help!
