a Hobbico starter doesn't have enough torque to start a new 30 sized engine and only well worn engines larger then a 30. you can partially remove the glow plug to allow compression to 'bypass' and then re-tighten it after it gets started. I've used this many times helping newbies in the past. after the engine gets broken in the Hobbicos will most often start them (30's not 60's).

My Hobbico TorqMaster 180 has been starting everything from new 0S 32's to new Saito 82's. I think there are different sizes of Hobbico starters. I agree with kc, if there's something keeping the engine from turning over like being flooded ... a smaller starter won't cut it, however, a bigger starter may break something in the engine.
For the record, looking down at the starter socket, counter-clockwise rotation turns the engine over ... clockwise spins in the one-way bearing. Kinda makes sense since the main rotor spins the opposite direction due to going through one reversal of gears.
The starter spins the same direction when starting an airplane engine ... counter clockwise as viewed from in front of the prop.
Good Luck,
