Thanks for the sugestions guys,
A few things I have done, I made a point to blip the motor berfore entering the sweeper...our sweeper is know for that, meaning you must blip a couple of times before you enter.
The second thing I did was alter the fuel presure line...it was quite short to start with so I thought that was the problem and lengthened it considerably.
The compresion of the motor is sweet
A number of things I did notice today after close inspection was the following. The front ruber seal on the bearing does not look healty

secondly I found that after I took the head off there was no shims or anything under the turbo plug (is that normal?) and lastly when I put the carb back I saw that it does not go right down...meaing the botton O-ring in the block is "blocking" the carb from going right down and thus the top o-ring is not sitting right against the block at the top....my theory...engine is cold and it seals ok but engine gets hot, it expands and thus starts to leak....does that sound right?
So took the bottom O-ring out to see what its problem was, not sure if I was suppose to do that because I can't get it back in
SOOO to cut a long story short once I get it back I will try fresh fuel and see what happens.
Thanks for the help so far guys much appreciated.
