Default roto starter MAGIC touch!!!!

i dont have a roto starter, instead i use a drill with a flat head screw bit. my problem is that when i use that to start the engine it wont start and i hear people say that u can use a drill instead of a roto starter. today i went to the local shop to see what the problem is and there was no problem, the guy just used a ROTO STARTER to start the engine and he even sayed u can use a drill. i know ur thinking WHY DONT U BUY A roto starter but i see it useless if i can just use a drill. is their some kind of a special feature in the roto starter??? cant i just buy the extension bit that they have for the roto starter and put it in the drill????

I belive the roto-starter has a clutch that lets the engine spin faster then the motor. After it starts it, it then probably stops it due to the drill not spinning as fast as the engine.

I ran into a similar problem with my Hudy breakin bench. It comes with a drill adapter so you can spin the prop with a drill.

A freewheeling ac drill starts the motor fine but a cordless DC drill with brake will not. I think it holds the engine.

I just use an airplane starter now or flip the prop by hand.





ps: bumpbox- ofna truggy

Doesn't roto start backplates have a oneway bearing so that when the engine starts it doesn't create drag.

a bumb box is a starter box.....a electric motor or pair of motor's sit's inside and spin's a wheel which you touch on the flywheel and voila motor starts.

like this

Roto start isfaster than torque start but box starter faster than both. My brother ran into a problem were the tourque was not fast enough but the roto was, but he still steals my box starter once in a while.
