Fueling

[webman12]

My cousin owns 86 CJ4 .2l with a holley 2 barrel nd problem is every time i shut it off it runs on for a couple seconds i have leaned out the carb as nuch as possible i have lots of vacuum whats the next direction I should be looking-Timing maybe to far advanced ?

Sounds like too much advance in the timing, does it ping under a load ?

Leaning out the carb could make it worse by making it hotter.
Sounds like the timing is to far advanced, it should be around 6 with the vac. line disconected.
If anyone has ever done anything to raise the compression you might need to run prem. gas.
