I cant say I paid much at all for a starter.

For a 40 size engine it can be one of the smaller cheaper models too....

"BUY RIGHT, BUY ONCE"
Can you honestly tell me you'll go to all the effort of finding a way to use a drill to start the motor and you'll NEVER buy a starter in the future. Buy it once and its "done".

save up and borrow in the mean time, and when you have finnished borrowing, make sure the owners know you are greatfull.
