What a Meshhh!

What a Meshhh!
The number of teeth on each gear is marked right next to it:
If the gear G1 makes one full revolution clockwise then how many revolutions will the gear G2 make?

My first thought was that since all the gears on are on separate axles the intervening ratios don't matter; 21/7 = 3/1 and so G2 will make three revoloutions for every one of G1.
Then I noticed there are an odd number of gears in the loop containing G2 and so it is frozen and none of the gears can turn at all!
