[QUOTE="Write2Paul90277, post: 185888, member: 3682"] . . Help! My 84 GL1200 Interstate is currently experiencing that ol' stumble-off-idle / bucking transition between 1500 RPM to 2500-3000 RPM. Also, it takes FOREVER for the engine to warm up. I have to fiddle with the choke constantly just to get it to pull from low speeds without shuddering , and I'm not talking about the first few blocks or a miles, but halfway across town. (Thermostat is fine, BTW) After searching the forum and Google for the Idle Drop Procedures (and trying them) none of the solutions works. I thoroughly cleaned the carbs (new jets, O-rings, etc.) and synchronized them using dial-type vacuum gauges. Spot on. When I performed the infamous IDLE DROP PROCEDURE, I used an external digital tachometer, but the digits just bounced around and were of little help. When I tried the "LISTEN FOR THE HIGHEST IDLE" technique, I really couldn't hear any difference in the engine speed as I adjusted the idle mixture screws. QUESTION: Is there a "typical" setting for the four idle mixture screws? I've seen suggested settings ranging from 2 ¼ turns (out) to 3 or more turns. Has anyone just set their idle screws to a certain number of turns and then SKIPPED the whole Idle drop issue? Am I dreaming? Is there an easier way out -- without converting to a single carb? Curiously yours, Paul . . [/QUOTE]
