This is really great guys! Thanks so much for helping me with this one. I have just returned to the PC after reading your replies, i grabbed the nearest flashlight and a 1/8" cabinet-type screwdriver and headed to the garage on a mission of discovery. Having located the idle mixture screw for the #1 carb (I think) rear carb on left, i was curious to see what i'd discover by turning it CW until very lightly seated. Was i surprised when it was 4 turns CCW from very slightly bottomed in the seat. Well, i proceded to back it out 2 1/4 turns CCW from very slightly bottomed. Now i'm excited to check out the other 3 but as i'm sure you guys know, i'll have to remove the lower fairing pieces that coverup the 2 front carbs. I picked up this bike (1984 Venture Royale) north of Denver last May and rode it home to Houston with it running pretty badly so I've been trying to learn about these pesky screws to adjust for many months. Having read many of the 'threads' posted here, it took me until this afternoon reading someone else's thread, how to write a thread and how to reply to one. I know it sounds pretty dumb, huh?!! )
Thanks again for the tips!
