.035 should get you going, but I haven't used those plugs for 20 years. What did they tell you? -
O'reilly didnt have Autolite plugs a lot of people have recommended.I have ran these before but on gas at .030.I wasnt sure if gap needed to change with different fuel. I'll try.035 and keep an eye on them. ThanksComment
