Well Again Track testing day #2: Failure!!!

Brand new glow plug #3 today. Still Engine does not idle, stay running, or keep tune. It is spitting fuel and burning fuel like no other. Settings are the same as last time I wrote. I bought 2 Plugs from Tower and they are 97T. They both went in 5 tanks each. I dont know why or what is going on. Now I lost some Compression to from this. I couldnt turn it over at all really by hand, and now it is a little easier. My buddy could not believe his eyes either. He has seen this Mil run and go strong. I dont know what happened or why this is going on. But I am very upset that I cannot race this weekend. little happy I didnt go away and race this past weekend. Would have been a long time wasted. Well Dont know what to do from here. Try another plug maybe? I just dont know. Stuck, confused, and most of all worried.
