As a back story\, i had some trouble with my 235 a month ago and as part of the diagnostic they removed the E-3 plugs i had in it and replaced with the ones that was in there before i replaced them with E-3s. i had the head worked on and new valve guides that were supposed to have been replace with the first overhaul. they did not replace the E-3s which i had forgotten about. i was watching a program today and he mentioned E-3s so i checked and the old ones were still in there. my gas mileage had dropped off by 5 miles to the gallon and i did not know why. i will see if this make a difference as it did before.
