Just put new Weber 34 ict's on my stock 1600cc type 1 trike. From the factory it came with 60 idle and 145 main. On adjusting the carbs to Weber's specs the left carb mixture ended up at 2 and the right at 1 7/8 to the best of my ability which is in the middle of what Weber said it should be. The instructions said to set the idle screw on 1 3/4. It said to not going in on the idle screw no more than the initial setting. My problem is my idle is to low ( 500 to 600). Has anyone had this happen to them and what did they do to get the idle up.
I have read about drilling a 1mm hole in the butterfly helps but I don't want to start drilling unless it is necessary. Any suggestions would be appreciated.
