Tune up after questions

I just tune up my 7, i change the oil grade from 10w30 to 10w40 and put brand new sparkplugs. here is my Problem before i put the spark plugs, my 7 was running normal and poping flames at high rpms, well now i have put the new plugs it just runs nice and smooth but i miss the flames. Does anyone knows why it not poping?

No the oil will not play any role in it. It is simply the amount of fuel delivery and unburned fuel passing through the exhaust.
