Bike won't roll backwards!

[jimbob83]

I've got an 88 ntv rather high mileage. If I try pushing the bike backwards it sometimes stops dead. If I raise rear wheel off the ground it happens turning wheel by hand. Not had bike on the road yet it's been sat for about 3 years

Sounds like it's not actually in neutral?
Should roll back without any problem, otherwise I wouldn't have been able to get it out of the shed every morning
