I am new to the forum, had a stupid attack last time I fueled my 630. Didn't check the end of my fuel hose, had some bug's, mud, etc. Sent it into the tank (found out when I unhooked it). Now I can't get my old tried and true 630 to fire. I have the service manual's on order. Don't know what I am doing. Any suggestions about taking apart the fuel manifold on a 630? I sure would like to keep from blowing myself up.
