Carb Help!!!

Thanks for all the feed back guys I really appreciate. I guess im going to take her apart over the weekend and see if I can get it to work. If I decide to put the 800 back on what suggestions do you have to make it not run so rich? Timing? I dont mind using the 800 but my wife and kids dont like riding in the car because the gas fumes are so bad. It literally burns your eyes! Also with the timing, I timed it at idle with a timing light and the mark bounces between 9-10 BTDC. Is this correct or incorrect way to time it? I have a stock timing chain cover on it so the timing marks only go to 10 I believe. These are two areas I am totally lost on. Thanks again and hope I am not asking totally ridiculous questions here!
