I've been searching through the forum looking for some general info on fixing up my new (ancient) bike. I picked up a 1980ish KH100 for stuff all. It would start only for a stroke or 2 if i poured fuel directly into the carb. so after getting the carb off i pulled it apart and gave it the mother of all cleans, the thing was disgusting, the floats were covered in green deposits (im assuming copper rust) as were most of the little bits inside, all cleaned and put back together. Question 1. Given the age and the filth etc do I need to replace the gasket in the carbie to ensure there is no vacuum leaks? Once I put this back on it would start and idle no problem on full to Â½ choke but would stall when the choke was off. It also dies if the throttle is twisted quickly. I have now pulled the head off and am carefully cleaning off some of the carbon deposits. Question 2. Where can I find plenty of useful/general/basic information on working on my bike? What to be careful of damaging, what parts to replace, what to check for, how to check things are working as they should given I have pretty much no experience in this sort of stuff and am teaching my self as I go. Any help would be greatly appreciated Cheers Hadyn ps, the spark plug seems to be getting covered in fuel, does this means is runnign to rich? and how do i get it to lean out.
