Probably not an ounce as I used a dropper from our vet. Yes, I pulled each plug, grounded them to an engine bolt and saw spark. I also checked all valves, had to adjust one, all at .1mm. Pulled plugs after testing and all were dry. Not even damp.An ounce of fuel is about 100 times too much, amazed you didn't get a hydro lock. Are you sure the plugs are firing & in time?
