Finally had some time to get my facts straight on an idle problem I've been having and need some opinions.
Lets start with the revs above 3,000 RPM. Release the throttle, and it idles at 1,200 RPM, a bit quick but smooth. If you blip the throttle smooth acceleration.
If you leave the throttle alone, after about 20 to 30 seconds the idle drops to 1,000RPM and its not really what I would call a smooth idle. Almost on the edge of stalling. If you blip the throttle, there is quick flat spot (almost stalling), sometimes a backfire, then normal accel. Upon release of the throttle, back to 1,200 RPM and the process starts over (i.e. after 30 sec, down to 1,000 and running rough.
I have Thunderbird pipes and 45 pilots (the pilots on the recommendation of a local Triumph mechanic).
Before I start playing with the carbs and perhaps going back to 42 pilots, would appreciate any suggestions as to what might be causing this problem
