Thank you for your quick response.
Just tried your solution.
Ran for about 20 feet and then flooded out.
Again, thanks for trying!

Hi, I had simmilar problem with my 1993 JGC . I ran out of gas and it would not start until the next day. Then it will start and run until I put the brakes on tho stop and then it will die. It starts right back up. Ended up being the voltage regulator in the ECC/ECM. It is at the mechanics shop right now waiting for the ECC to come in.I will post a follow up.

If you have a two line fuel system make sure the lines didn't get crossed. If they are you could still get gas to the cylinder but not enough. I hope this will of some help to you. Donnyb60

If your jetting is too rich it will be extremely hard to kick start it and will most likely flood it from kicking.First thing i would do is pull the top of the carbs off (cable,slides and needles) and see which clip they're set at. If they are set stock which would be middle clip then lower the needle one clip. This will lean the mix out and should start up easier with no problems,The idle issue is most likely just off.If your fiance still has the TORS on it then on top of the carbs he will see 2 dime size and screws and wires as soon as he takes his seat off.While running he can turn each dime size screw in or out to adjust the idle. If it has a TORS elimator kit on it then he won't have all the junk on top of the carbs and it will be just a cable and round cap screwed directly on top of the carbs and the idle screws will be on the side of each carb (brass color screws with nuts to tighten) same thing...in or out to adjust the idle where needed.Hope this helps.
