hey guys,

I have a question about the CCC quads, I have rebuilt the carb using all of damon's suggestions except the rods and hangers. I have the tuning gauges for the carb and set the lean stop, the rich stop and the IAB valve to they're specs. not sure of the idle mixture screws though so went 4 turns out from bottom. I hooked up my dwell gauge to the lonely green connector near the fire wall next to the heater fan, the question is ??? the dwell gauge shows a steady 27* and nothing I do seems to make it waver at all, I tried the mixture screws and the IAB and nothing changes it. did I miss something or can there be another problem ????

 

The ECM will not start to adjust the M/C control soenoid until it goes into closed loop mode (the O2 heated up). Until then it sends a constant duty cycle signal to the carb.

 

thanks Damon. I forgot to mention that the motor was already warmed up prior to trying the test, we had driven it about 25 miles just before. I have already replaced the 02 sensor when installing the new motor, the motor runs better than ever but I wanted to make sure everything was correct. I anyone has any ideas on this please respond !!!

thanks again.

 

Hey Redbird, did you ever figure out what was the problem? Mine is doing the same thing.

thanks,
