Pictures from taking the carb off the bike and taking it apart to puting it back together and some info. on how and what it all does well sort of and ways to change the min jet for those who want to and areas that can bite you by plugging off and sort of how to fix them. I hope this will sort out your questions if not let me know. I think this is a very nice and simple carb I think its great some of you hate it, can't make everyone happy. Here's the pictures.
The pencil is pointing to where you can turn this out and take up some of the slack on the throttle cable.

I wanted you to see the IDLE SCREW and the little throttle slide guide and the fuel tickler, push it down for a few seconds and it lets fuel in the carb for a cold start along with using the choke. I don't use it myself.( the tickler)

.026 is stock dia. of main jet on my carb to go leaner solder shut and drill smaller my suggestion is one size at a time. Most adjustment can be made with the e-clip on the needle. This mostly affects 1/3 to wide open and very little on the idle. If you can't get it tuned with the e-clip and want to go richer make sure of your stock size then drill the next size bigger then test your bike.

pointing to the place where if you get trash in the tank and no filter this is where it will get to first and cause the engine to flood you got to take it apart to get it out. this can be removed by taking off the fuel line and unsrcewing the fuel inlet pipe carefully and don't loose the red gasket hard to make and will leak if you mess it up.
