I mounted the tank right in line with my other tank, which ends up to line the top of the tank up with the midle of the needle valve. have checks the lines and ran new ones. screw in bottom of muffler is expoy in.

Engine will not start unless primed by holding findger over muffler. once started, it only runs for the amount of time that the priming puts fuel in the cylinder, which is about 3 seconds. This whole time it is running very lean. then it dies. It obviously isnt getting fuel (compression).
dont know why at all..

Who would have thought that a lously header tank would have taken so long to work out the problems. Easy 5 minute job....

Also, I have changed the picture at the top to a current one of my setup..I see no reason for this not to run perfectly.
