Ok so i have a 1998 J70 TLEC. My question, out of some fun curiosity. My engine runs good. I did a bunch of work on it myself. Thanks to this forum. I had a couple of problems and they have been fixed. How much better would a carb(3) be if you replaced the covers, needle(3) and gas and air orifices? My common sence tells me that 100’s of gallons of fuel had to of gone by over the needles of the 3 carbs, does anyone beside me think that these parts may have worn over the last 20 years? Were talking roughly about $75 for each carb. Do you think it would make any noticeable difference? A slow speed adjustment needle alone costs $40. Just curious.
