Put all new belts on it and a new generic EBay carb. it runs good and the plug looks good now. I might adjust the governor linkage a little in the near future but want to run it some more because it was sitting for some time before I bought it. The mower creeps slightly while in the center neutral position. It's not a big deal but if it is a simple alignment I'd like to make it right. I was able to go to Simplicity's site and download a parts and owners manual but pages 21-30 are missing and that is where the alignment instructions are any help is much appreciated!
