Jpar, what’s your octane rating on the fuel being used?
I swear the last time yr made a plug recommendation it was hotter plugs LOL
I think he'd love to see me chasing my tail...
(I'm going to need more than a picture of a rusty r-block on the floor and a no-show...)
The summer I tried just running straight 92 non ethanol from the pump. As soon as the race gas send out I was starting to get some run on when I shut it off. So now for every 4 gallons of 92 I put in one gallon of 110 Sunoco. About 95.5 - 96?
