I had a Valve job done on my /6 and got the thing running and adjusted the valves. The next day I came out to tie up some loose end and could not get it to start. It would fire then immediately[sp?] die out. I have spark and good fuel flow!! After thought, I did a compression check. The dail would go to 100 then fall just as quick back to 0. I unlashed the valves thinking that might be it but no luck. I even swapped head gaskets again thinking I dicked up there and still no change. Am I overlooking something or do I have a bigger problem

i'd double check your valve adjusting, how did it run after getting the valve job done? how many holes are low on compression? i'd bet that there are a few valves that aren't closing completely...
