Has anyone got any experience with Barry Grant Demon carbs? We were running the engine on the dyno to day when it developed a backfire through the carb. We switched carb and distributor/coil system. Smooth running. Put my distributor/coil back in with shop carb, smooth running. Dropped my demon back on and backfire again.
Tomorrow gonna pull carb apart clean and take back to dyno. Carb is new min hours. It did suffer the bad fuel issue though. Any suggestions with the carb would be appreciated.
