Hello,
I have a new lycoming with supplied carb and was wondering about making adjustments to the carb idle and mixture. This was installed on the lycoming with supplied basic instruction and after first engine start the idle just seems real rough. That rpm is about 500 to 600 and I'm wondering if I should adjust it up to 800 or not. If so, should any adj be made to mixture first? I should also add that upon engine shut down, the throttle back and then pull mix to full lean, the engine takes its time shutting down, possibly only 2 or 3 seconds but it just seems like a long delay. I also don't have that slight increase in rpm just before as is ideal. Can someone comment on this and provide some guidance. I could also use some info on how to make the adjustments. Like if engine should be running and then turn set scre located xx 1/4 turn.. Something like that. I don't have a maint book for the carb so I'm what others have done as well. Thanks!
