Since, I have made up a lot of various size jets and found the exact combination that works for my current engine condition. I went on a 10 mile run this morning, car fired on first tap of the starter and all is well. Love the #18 plugs - I ordered mine through Napa and the had them in two days. It took alot of effort, however, the end result was well worth it. ps making a sized jet takes less than five minutes. Have fun with your "A!"
What is an 3x-16 and 3x-18? Are you talking about Champion W16 and W18?
