70 JD won't start

Posted by brians in sd on March 18, 2012 at 19:47:13 from (68.69.84.227):

I installed a diaphram kit on the fuel bowl assembly for my 70 JD gas. I poured in a couple gallons of fresh gas and got it started, but it was missing on Number 1 cylinder, so I shut it off. 'No sweat' because plugs foul up easily on this tractor and it is common for me to wire wheel clean them or sandblast them. Then it starts and runs perfectly for a good number of hours. After I cleaned plugs this is where the plot thickens.

With plugs cleaned, now the tractor won't start. Every once in a while there is just a hint of a fire on one cylinder, but that is all. Now, I have gone from believing that it is not getting any gas to believing that it is flooded. I have taken out the plugs, dried them, and cranked it to make sure if it is flooded, that I have ran excess gas out of cylingers.I have also screwed out the plug on bottom of carb bowl twice, and had gas gush out of it until it drains the bowl. I have checked during cranking to make sure the little spring loaded stem valve is going down to allow gas, because I put in a new rubber washer, and it seems to be working. Anyway, I can't rule out flooding but it is unlikely that it is not getting gas at all. The tractor has always been a good starter and runner, and all I have done is worked on the fuel bowl assembly. Any thoughts?
