Hesitation issues - need help

10 degrees is a bit low on timing, clue was you said it was hard to start afterward. I run 15 initial and 34 total mechanical with my stock cam 318. Getting your initial timing and fuel level sorted first as suggested previously would be a good starting point. Writing everything down in a log as suggested is also a great idea so you're not chasing your tail and forgetting where you're at in tuning. Do you have a vacuum gauge?
