Congrats excellent job! Sorry I must have missed that about it being a manual trans. So in that case you will then also need to reset the carb's Curb Idle RPM higher in the range of 500 to 600 RPM experiment and see what it likes 525 or 550 usally is about right. The base timing can also vary some 10 to 12 degrees BTDC is a good starting point you can also try some more to see what your engine likes. It might be as much as 14 to 16 degrees any hint of pinging under a light load back off some timing. Remember if you change the base timing you will also need to reset the #4 the lean best idle setting. Good luck
