Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I recently purchased the S520E snow thrower from Home Depot last week. The problem is that by error I put in too much oil. I looked at the manual which said to drain the oil by unscrewing the oil drain plug. The oil drain plug does not seem to budge at all. Is it meant to be this tight or can I use a good bit of force to open it? I just want to make sure that I am doing the right thing here and not going to cause any mechanical problems. Any help would be greatly appreciated.
