runs for a few seconds and cuts out

Hello all,
I believe i have a carburetor issue.
backgroud:
boat flooded, water in motor.
cleaned up, engine head was found to have a water jacket breach. head replaced. 90 compression in all four cylinders.

while working on replacing the head. a co-owner of the boat decided to rebuild the carburetor with a moyer rebuild kit.

threw everything back together and the engine starts (with choke out) runs for a few seconds then cuts out. wait a few minutes, same thing.
i can keep her going for a little longer by spraying some carburetor cleaner in the intake, or pouring a little gas prior starting into the carburetor. I messed around with different idle mixture settings and throttle settings and some difference but no real results.

drained the float bowl, cranked and ran for a bit after pouring a little gas in carb. checked float bowl again and full of fuel, so manual fuel pump seems to be working.

i pretty sure I have good gas, had flushed gas threw after throwing all together and she does run for a few seconds.

so i now have the carb off and going to take apart. I have a few questions:

1) gasket sealant? i do not see anything in the moyer manual in regards to the gasket and using sealant. anything i should know about this?

2) the moyer manual mentions the main jet can easily get damaged. How do i tell if the main jet has been damaged?

3) thread sealant. should this be used anywhere?

4) anything else i should particularly be looking for.

any other advice greatly appreciated.
thanks,
tom
