When you applied the fuel and it died its important to know at which point and under which operating condition it died. When you start the engine the fuel is fed through the pilot jet up until almost 1/3 throttle at which point you transition from pilot to main jet. If the pilot is too small or restricted this will cause it to die when normal throttle is applied, more so with quicker acceloration. First you want to be possitive without doubt that the 1) valves are adjusted correctly with .003 int. and .005 ex. cold. 2) you have no vacume leak at the intake. When you drilled the main jet unless you have metric drill bits and had personally checked the bit you used to a 130 jet you cannot be certain on how rich you made the jet. When you say @ 3/4 throttle it boggs down, this sounds like it is jetted too rich. Pulling and inspecting the plug immediately after the 3/4 bogg will tell that story. Back to the origional dieing off idle, if you throttle very slow and it seems like starving but then you get to the point over 1/3 throttle it gets better then the problem is either restricted or too small pilot. Just from you stating rough idle will make me look to vacume for leaks or valve adjustment ( too tight). Too get the engine to idle at its smoothest and highest idle how many turns from the seated position was the A/F adjuster turned out. If your unsure on any feel free to gine me a call this evening.
