| noo no no no,... u know them little electric motors u find in them portable fans??? well ur electric start is just a really big one of them,... and that have magnets in them,.. thats how they work,... and the crank shaft goes right threw the middle,... the the drive shaft of the portable fan,.. when the elec start isnt turned on,.. the magnets are trying to hold the crank shaft coz that are magnets and pull metal,... so when it isnt in use its trying its best to stop ur crank shaft from moving |
