bdrought,
i have never seen this plug being blocked off. If yours is, you are looking at the wrong one. I must comment though, it sounds like you did overcome the problem with a little back yard engineering... I love this site. If you find the right plug, you will be able to permenantly adjust it and forget it!! It will then start every time.
