[vornato]

After installing spark ignitor, I find there isn't any gas flame to one burner. I lit a match to it with the cap on and a very large gas flame shot out from under the main burner top, after turning gas knob down the flame subsided. I guess there is a restriction of some kind causing the front main burner not to ignite. I can hear gas when I turn the knob to ignite, but it isn't as strong as the other burners. And I assume I have to remove the main top to do this. A lot of work. So, I guess what I am asking is, does anyone have an idea of which part the culprit may be that is causing this. I know the orfices and chambers that allow the gas in probably need cleaned. Thanks, for help!
