Default rm250 problems

just bought waht i think is a 1984 rm250 it has front and rear drum brakes.
anyway it starts up but when you rev it, it doesnt get into the powerband it just splutters, also when you let off throttle it seems to take a long time for the revs to go back down
the throttle isnt sticking
it also backfired so could the ignition timing be out? iv looked but cant see any timing marks

hope someone can help
thanks
scott
