Yes, you can flush a freewheel while it's on the bike, it's just a very messy process. Place the wheel flat on the floor (outside is best, and/or use a plastic drop cloth). Direct the spray at the gap between the turning outer body (sprockets) and stationary inner body. Spray and let it run in, helping by turning the sprockets. Repeat until you see it dripping out the back, and the sound changes. Spin the freewheel, allow to drain, then oil it the same way. Now begin the long process of wiping solvent and oil off the spokes and hub.
Note this method isn't usually suitable for freehub/cassette systems since it's likely to also flush grease from the axle bearings.

It's not whether your chain is too long or not, but whether it's too worn or not. Search "chain stretch" here on the forum or elsewhere on the net to learn how to measure the chain's wear.
