Coleman Powermate 5000 Generator won't start
I have a Coleman Powermate 5000 that I purchased in 2001.
It won't start.
The rope turns the flywheel and I get a backfire.
It has fresh gas, which is making it to the carb, a new spark plug, cleaned carburator.
What am I missing or doing wrong?

You did not say how you cleaned the carburetor. If you did not remove it from the engine and disassemble it, I would do so. Just spraying cleaner at it or down the throat will not do much. You have to clean all the tiny orifices, passages and jets.

Try removing the plug, adding a tiny bit of gas in the cylender head and replace the plug. Should fire and hopefully draw the fuel from the carb.
I think these have a fuel shut off, is it open? I own the exact same model, but can't remember if it has a shutoff.

It does have a fuel shutoff but it is open. I checked the flow when I pulled the carb.
I pulled the plug and added gas with the same result, no start.
The strange thing is that it backfires.
So, it looks like it's getting fuel and a spark.

Does the engine have compression? The backfire indicates a valve open at the time of firing. Could be a stuck valve or an ignition timing problem (possibly flywheel key).

I had one of those, does it have the Subaru/Robin engine?
If so, the valvetrain is chain driven and very easy to access. Pull the valve cover and observe the timing marks.
I am with the big Cheese on this one....could you have sprayed into the intake and knocked a piece of crud under a valve?
Backfire is either from the intake valve stuck open or timing is off......both holding the valve open slightly.
Page 23 shows the timing....providing you have the Subaru/Robin engine.
