There are engine rebuild manuals you can purchase that cater to the 22r or toyota engines. There are also videos you can purchase online (ebay) that show rebuilds or guide you through. You may be able to google search a complete build up.
ive looked all day online and havent found any text/pic guides. i cant download a video, my cell phone has a data limit and i dont have any other source of internet. this is my absolute first time doing any type of carb work :/
