93 DS - starting/running issues

[mitchntx]

Cart was running fine a month ago. Using some oil, but would start and go.

Then it began oil fouling plugs and needed oil every 3 or 4 days.

Then, with a cleaned plug, it got to the point it would start and run, but after a couple minutes it would sputter and die. Restart and repeat.

Finally it died and wouldn't run.

Been reading here and everything pointed to a failing/failed fuel pump.

Bought a replacement from a site sponsor, the owner installed the new pump and no fuel output.

Vacuum checked and it pulses instead of sucks. Is that right?

I'm open to suggestions ....
