It was a pretty day in Oklahoma today I got a lot of things done and screwed a few things up must have been that 6point beer I brought back from the NASCAR race in FT Worth last week. Anyhow the bike was running good and I being the dumb a** I am I decided to adjust the airscrew should have left it alone. Anyway I didn't take a starting reference so I am not sure where it needs to be and it won't idle on its own to adjust as I have read. I have a 86 the book says it should be 3 turns out from fully screwed in but that just caused gas to flow from the vent tube and a very rich looking very rough idle. I say it looks rich because as it approaches’ dying it puffs black smoke and dumps gas out of the vent tube that is on the same side of the bike as the screw. The carb is stock. I have a semi-hollowed out stock pipe and the cover of the air box removed at about 600 ft above sea level. Any ideas on where it should be from all the way screwed in? I need to get a sporty muffler and an k&n and get the Edelbrock carb I got from lancer on my bike, but that is two or three weeks away and I need it rideable now. I have researched it and can’t find enough info to insure the bikes I read about are similar to mine. Thank you for your help in this matter. 8)

forgot to ask should my 86 have a white spacer I got the bike used and it didn't. I am thinking that may be the real sorce of the problem. I know that the early models are different for example my bike was stock with a 155 main jet wereas newer bikes have like a 152. so is the white spacer something they started later in production? 8) Thank you all

yes sir if you can find it that would be great I have been tinkering and turning trying to fix this problem if it is just a little plastic washer I am going to be pissed and happy at the same time as long as it fixes the problem. do you have a link to the fiche that shows that washer to make sure I put it in the right place. I am pretty sure of the location but would like to be positive. I may also try the 2 #4 washer trick and see if that helps. I can't belive I didn't ask this question earlyer I just assumed that with the different jet my carb was different. ???      8) 8) 8) bobo your a life saver 8)

Mine is best at 2 turns out from the stock location. However, that is with open(ish) pipe, stock spacer, and stock jetting. I know that I SHOULD increase the fuel flow with the open pipe, but I'm unwilling to cut my mpg. The bike runs fine as is, so, I'll mess with the cosmetic junk all day, but leave the carb alone. Besides, I break out in spots everytime I even THINK of opening the carb. For some reason, carbs or EFI and I don't get along very well.   ???

Mine probably only runs okay because the air filter is dirty enough to richen up the fuel mix. As soon as I add a new filter, I'll likely have to tinker with the carb.  :'(

Thank you all This will help in the troubleshooting I got the #4 washers hope to put them in this week I will let you know how it goes while I am doing that I have a inline filter to put in also.  8)

Link to the Ron Ayers Fiche:  http://www.ronayers.com/fiche/300_0039/carburetor/carburetor.cfm?man=su&group...  The "turns" term is from all the way in.

item #6 in the fiche

do not forget that there are rubber parts in the petc0ck that can wear out and emulate a carb problem.

that said, does it flood when set on "prime" as well as "on"?
