I have an 86 CJ7 258 w/ Weber Carbs 32/36 and MSD Ignition. Just to get it runnning I removed/plugged all the vacuum hoses and control. I get a bit of hestitation and backfire at this point and the plugs indicate I am running rich. Do I need to worry about this because it will change when I add...
Is there any reason a 86 head wouldn't fit on a 79 block for a 258 jeep engine? I know the bolts are bigger for the 79 head but can I bore the holes on the 86 head by 30 mils to make it fit?
