I would Humbly suggest:
1. Current fuel has alcohol, which burns hotter than previous fuel, a ac44 should be the Hottest spark plug you use.
2. Run a 170 thermostat, for same reasons as above.
3. Should be able to run a 12 degree advance with a 32 max ( just a base line range here)
4.Check your vacuum advance with a mighty vac if its been sitting a long time
5. Check your brake booster check valve as well ( vacuum leaks)
6. Check all vacuum hoses
7. Grab some ZINC additive for the oil, and dont use anything with 5 weight ( example 5-20) use a 10-xx oil
Good luck!!
