Dump the water separator into a clear container, anything but clean perfect fuel will tell you what the problem is.

So first is find why it gets no gas - this is same as a car - pull the line off the carb and stick it in a bottle. Crank the engine, anything come out? No - fuel pump or plugged line. Yes, the screen on the carb or the needle valve is crudded up.

overheated

When was the last time the impeller was changed?

With an overheat and if it was running before then do a compression test

Checked the compression and it was bad in 3 cylinders. Guy told me motor was done. Now I’m trying to figure out how and where to find a new motor. Any suggestions.

Several places to get reman's but what about having yours fixed? If it was just an overheat, most can be fixed with a head and valve job

They guy that checked it said the motor was junked. I haven’t had much luck finding someone to do it. Didn’t know if it would be better to just get a another motor. I really appreciate the help.

That doesnt explain why you arent getting gas or fire. Is it fuel injected? Computer controlled? Maybe a fuel pump cutoff switch. What was the compression? a simple head job could fix the compression issue so a leak down test is needed. Since it overheated it could be stuck rings...some marvel mystery oil helps alot unsticking these. You can put a brand new motor in it but if your not getting fuel or fire that engine wont run either.
