you need a timing light and on the front of the engine youll need to look for the timing marks usually in 5 degree increments you'll advance the timing by loosening the distributoe and turning it till the markk on belt matches up with what you want.i wouldn't go more than a couple of degrees to start.there should be 1 bolt on dist to loosen.

when you advance timing you are asking the engine to spark the gas earlier than what its set at

advancing your timing will do no good,for one reason you are in a higher alitude and need adjustmas to the thiner air.

You can change the ignition timing in cars you can change the position on the distributor, but in your jeep they change electronically!
