    i did end up spraying starting fluid into the carb
    and it did turn over and run for about 10 sec and quit.
    i took off the vaccum pump and blew into each line and pu the vaccum pump back on the tractor. i sprayed a shot of starting fluid again into the crab it started and stayed running only if i held the choke all the way out. what is causing me to hold out the choke? if i release the choke, it quits.

    Holding the choke closed richens the mixture. The fact that you need to do this in order to make it run means that it isn't getting fuel or at least the proper amount. There are several things that can cause this. It can be as simple as having water in your fuel to plugged ports in the carb. to a fuel pump and the list goes on. Cleaning out the fuel tank and carb. will fix the majority of these type of problems.
