Could be the pump. Mine did the same thing. I could pour a little gas in the spark plug hole and she would fire right up, but cut off after burning the gas. I don't think a kit is available from John Deere, maybe from some other source. If you decide to take it apart, make sure you note how the two outer plates are positioned. I thought I had, but when it came time to put it back together, I got them misplaced, and it would run, but pump the crankcase full of gas. I placed them correctly and all was well. There were two little rubber umbrella shaped valves (the best I remember) that had become stuck to the center plate. Worst case, you may have to buy a pump. They are expensive, but cheaper than an engine. I would suspect if it runs well when cranked, it may not be the pump. Maybe the choke is not working properly?

I filled up the fuel bowl with lighter fluid and it ran great. Plus the fuel pump is missing one of the bladderes so somone has had it apart before. It was also put together in the wrong position causing the gas to flow into the block as you stated. There is a nipple on the 2 pieces that line up and the third piece which caries the vacuum from the block can only go on one of 2 ways as long as you pay attention to the center divider. I got the rebuild off of Ebay for $12 with free shipping and alread got the rest of the unit restored. If I had to buy a fuel pump then I would pass and spend the extra $150 and get the new one. The fuel pump at Deere is $50 and made by mikuni. Heres a pic of the rebuuild kit.

Could you email me the source for your pump kit? I'd like to have a spare for $12! Sounds like you got a deal. Hope it runs great now.
