How smooth is your idle?
I forgot what my stock motor and carbed sounded like. Can someone please refresh my memory on how our rotarys are suppose to idle? I'm now running a stock port GSLSE 13B with a dellorto and headers. Is my idle suppose to be smooth as in no skips or misses or like a cammed boinger. The reason I ask is because i'm playing around with my carbs idle mixture and can actually get my car to sound flat at idle(1000rpm). I mean flat and smooth but the car whole car shakes and shudders.
Thanks, Ed

have you played with timing? i have found that at idle normal 650-750 will have small blips that are normal but direct ignition jeff20b method will solve that, but if idle is at 900-1000 then it idles smooth with no blips the shuddering though pbly shouldnt be occuring. there is an air/fuel and curb idle screws if you adjust theam you can get it to idle about perfect i have took about an hour all you need is lonf apex tip screwdriver. good luck

love the braaaap
My car is a stockport, but when its warmed up it doesn't miss a single beat. Misses tons when its cold, but when its warmed up, it runs smoother than my moms 91 chevy van. It has about 100,000 less KM on it too.

stock '83:
(southern cali weather)
starts up rough when "cold", burps, sounds like a huge miss, etc.
after a minute of that, the tone cleans up and changes to be more "clear" like if i turned up the treble on an e.q.
Idles and revs suuuuper smooth for the rest of the time. Just had the carb rebuilt, so it better run that smooth! Lovin it, actually. The rebuild fixed my intermittent fuel-cut / fuel-lock problems, by the way. Ah, peace of mind is so nice.
