You need to invest in more tools, or be more creative with the ones you have. I've pulled intakes numerous times without pulling the dizzy, and yes, they had the throttle/kickdown bracket.
However, pulling the dizzy is nothing and probably isn't your problem.
Check around your intake to make sure you didn't accidently tighten a wire, cord, etc. etc. in between the intake and head. Pull the plugs and smell them... gassy?? If so, clean, dry out the cylinders by leaving the plugs out, check for fire at the plugs, and reinstall. Pull the carb off and inspect. Floats stuck and filling cylinders with gas?? IF so, look at your oil. Might be a good thing it didn't start if there is gas in the oil.
