Advice Needed - Can't Start Rebuilt 273

are you sure you are getting spark at the plug? maby the module or something like that has went south. it sounds like there is no spark so my first thought was the dizzy is out 180degrees but if you say it is in right then thats not it. when it ran a little is that when it would puke out raw fuel?

Yeah, when it ran briefly, it puked the fuel. I am 100% sure the dist is not 180 out. I'm pretty confident that the ignition system is not the problem because I pulled the running 340 and put in the 273 with all the same ign stuff. I'm getting spark to the plugs, at least until I flood it out after numerous attempts to get it to run. I have taken the plugs out several times to clean them and dry out the cylinders.
