89 Nautique no start after carb rebuild

Working on getting this boat back on the water after sitting for almost 5 years. Less than 200 hours on the motor. Well maintained and ran great before sitting while the local lakes were super low and I was too busy to get my ass in gear. Started by dumping all the fuel, replacing the ASV, dumping the separator (kept the filter because it looked like new still), and rebuilt the carb. Prior to doing all this I turned the key to see what it was doing (before really thinking about how old the fuel was), it would start to fire with some fuel dumped in the carb, but wouldn't keep running without lots of throttle. Also, no fuel making it to the bowl in the regular fashion. Hence the rebuild. Post rebuild, I've got plenty of fuel and decent crank with a new starter battery, but won't fire. Plugs are pretty black, but not awful. I'm starting to think that I messed something up with the rebuild. I was pretty careful and believe I didn't mess up reassembly, but maybe I am missing something simple? It's hot where I am and the choke plate is always at least partly open. So maybe I goofed up the choke? I pulled the rich/lean screws from the metering block  when I was rebuilding and just eyeballed reinstallation. And the power valve in the rebuild kit was 6.5 while I had the old 2.5 in there before. All suggestions appreciated. 

Yeah. From no fuel to too much fuel. Pulled the arrestor and disabled the choke (it is 100 degrees here). Turned the key and I can see fuel pumping out the primary vent tube as it cranks. At least the accelerator pump is working fine. 

I should have warned, if cranking while looking down the throat of the carb you may be exposed to having your hair burned off by backfire.  It does happen so do be careful.   Glad you found your issue.   

Sounds like it is flooded in a big way.  You might pull all the spark plugs and crank it over to blow excess out of the cylinders.  Look at the plugs, my guess is they will all be very wet and not able to spark.   

Checked the coil and good voltage. Before heading out to find a good condensor and points I figured I would check the gap. It felt a little loose on my 0.018 feeler so I reset it. And now I'm getting spark and it starts. I guess maybe running super fine grit paper through there messed it up just enough? Now I can keep it running above 1000 rpm with the throttle on a bit, but it won't idle. So I am thinking a new set of points are in order and I need to brush up my timing and such. So good news I guess. 

Got the idle sorted. Just needed adjustment. Probably at least a bit related to swapping to the 6.5 power valve. Now...I've got heat issues. Idling up to 180 off a bucket (with 85 degree water from the hose. It's hot down in Texas). Portside riser is much hotter than starboard. Tightened all the hoses and no change. I pulled the impeller and it's pretty chewed up. Does this look bad enough to be causing my issue? Replacing regardless, but wondering if I should be trying to get chunks out of the system somehow. Figured I would pop the new one in and see if the temps come down first. 

That impeller is TOAST!  Looks like it lost some chunks but they look to be small...hopefully nothing large.  You may get lucky and they all flushed out.  I would switch, run and keep an eye on temp.
