Anybody know about Idle fuel restrictors? I have a Mighty Demon 750. Carb is too big for the 383 without SC. That is coming next year. I have tried rejetting and air-bleed adjustments with no luck. CAR IDLES TOO RICH. Trust me that all the timing FP slots and the easy stuff is correct. I'm going to replace the IFR and I'm looking for a little heads up. This Carb IS too big for the engine. Should have jetted up from the 650.
Thanks,
SPK
