remove the glow-plug and brass washer, turn your truck upside down, and let the fuel drain out.

It just might be flooded. Afterwords, with the glow-plug still out, yank on the pull-starter about 3 times till it is not spiting out fuel.

Then reinstall the glow-plug and washer and try to start it up.

Make sure your tune-pipe is not blocked up with dirt via a tooth-pick or something.

If you did not damage the high-speed needle, it should be fine.
