Hello i have a 454 engine carburated. i tried turning it on today and a crank crank noise came from the starter area. it turned over once then it shut off . i tried turning it on again and i heard the starter making noise but the engine is not turning! does anyone have an idea what this my be? could it be the starter that broke its gear on the flywheel? it is a high compression engine bored 30 over. about 400 hp. it has broken starters in the past.but this starter is fairly new.i even tried to move the starter to see if it maybe was lose or something. but its pretty solid on the block. pease help thanks.
