I'm not positive about the 4 cyl. but if it's the same as the I6 just take off your air cleaner and as you hit the throttle on the carb. look down the carb and you should actually be able to see the fuel enter the carb in a mist. Also if I were you I'd check the timing because when I first bought my jeep the timing was loose so when i hit a hard bump the timing was thrown way off and the jeep kicked out on me and i couldn't figure out what it was until I checked my timing once again. Good luck with it, keep us posted.
