Jon, I fully understand. Two years ago, one of the pulley spindles went out on my Cub Cadet. I ordered a new set of them and belt. Getting the belt back on by myself was a miserable and painful experience. Then after just a couple mowings, one of the new spindles went out again and I had to get a new single spindle and install that. At least this time I had some experience putting the belt back on, but it was still a PIA. All said, I think I saved myself a couple hundred dollars in labor at least, but I am getting to the point where I am just not able to do some of that stuff any longer. I really like to do maintenance on my stuff as much as possible on my toys and vehicles. First, it can save a whole lot of money, and second, I know it was done and done right. I know the oil gets fully drained. I know the fuel filter "really" was changed. I know quality oil was used. I know the lube points were all really lubed. etc........
13 year old Cub Cadet and it is still running great and starts up every spring.....that is not to say I have not had some issues....but invariably, I get them figured out and fixed. I actually had a problem getting the thing started a couple years ago. Sometimes it would start and sometimes not. I eventually took it in and they could not find any problems. I left it there and since it didn't fail to start for them during one day, they said it was fine. Yah, I get it home and it won't start. Finally found a post online about the fuel cutoff valve. It is a device that shuts off fuel to the carb when the key is turned off. It is designed to prevent "run on" and backfires. Well, it tends to stick after a while and I replaced that two years ago and have been good since. After the shop said they couldn't find anything wrong, I was nearly to the point of scrapping it.
I am not saying I am a "professional", but sometimes it pays to grab a wrench and do a youtube search.
