Check for spark. That is one great motor

+1...might be an ignition problem. If you are sure you are getting fuel then check to ensure you are getting a spark.

First thing to check would be the spark. 4.8 volt ignition or a 4.8-6.0 volt ignition. If its solid gray case and 4.8 volt unit, you may need another one. (old unit) On to the other immediate thing to check: If you're not getting any fuel draw as you turn over the motor with your choke on, open up the carb and check to make sure the screen is clean and the fuel metering pin is not stuck with old congealed fuel. Clean out the carb really well with a fine piece of music wire. (Clean all obstructions with the wire and blow out
with compressed air.) I've got one of these and it's a real powerhouse. Good luck with the make ready...
We're all listening for that 3W bark real soon!

A couple of things to expand on here.................

Battery- If the 3W 60 has a "old style" ignition, uses a pick up coil to generate the spark to the module, the pick up will be a bit larger and will be black in color. It will have 3 wires coming from the pick up. If anyone remembers what the Futaba "G" series plug looks like, it will be the "servo" end on the pick up. The ignition system itself will either have a blue dot on the top label or it won't have. If it has a blue dot, then the highest voltage pack you can use on it is a 6V battery. A123, LiFE, or 6V NiMH/NiCads will work excellent. If it does not, then a 4.8V pack is all you can use. If you only have Lithium Ion/Poly packs, you can most certainly use a regulator, drop down diode in line to the ignition unit. There is no ill effect if using a regulator, unless the ignition has been changed out to the new IIS ignitions. It is a 4 wire system, and then any battery under the sun up to 8.4 V will work fine. If you are not getting spark, 99% chance that it is a plug cap.

It is quite possible that the carb is not drawing fuel. Possibly a pinched fuel line, collapsed, etc. Be 100% sure that fuel is getting to the carb. It is also possible that the carb is all cluttered up with crud and junk, and it just needs to be cleaned up and flushed.

All good advice here. You said your carb is new. Use the "Fore Play" method to make shure that new carb is good and wet inside. Just need to loosen the screw holding the pump side plate down and gently force gas into carb. The Jedi describes this in other threads. I had the 75 rear carb and it had sat for some time in less than ideal environment and I had to unstick the reed pedals.

bad?

I'm think now that the Ignition System maybe not be any good, because it sat in the barn for 4 years. I'm looking at rc extreme power, they have them cheaper then what 3w sell em for.
What you guys think?
Thank, Gerard

Any Rcexcel or CH ignition is better than replacing with a 3w ignition due to price. You can also replace with DA ignition but its pricey like a 3W.

don't waste your money on a new ignition until you are 100% sure that is the culprit.

Also check every connection on the ignition system. If it sat for 4 years, there may be corrosion on just one of the pins in the connectors. Does it pull fuel up the fuel line when you prop the engine over? Could be something simple!! Capt,n

Seat and reseat any plug in you have on the ignition, spark plugs included. It could be possible that there is a tad bit of corrosion on the plug ins. If you have to, inspect them under a magnafying glass.

Still, all good advice from the above.

All the advice above about checking the ignition is spot on. As is the question about whether or not the carb pulls fuel. (Does it?)

If it turns out your ignition is u/s - I strongly advise that you replace it with a unit from rcextremepower. I have converted a few 3Ws of various displacements over the years with those units and they definitely are the way to go.

Simple, If the prop hub has two magnets you need the two magnet ignition.

If your prop hub has one magnet you need the one magnet ignition.
