i have to replace the original starter.? i have managed to remove the three bolts (even the stubborn top one) and the terminal plugs, but the darn thing will not come loose. i hammered and used a chisel and even a brick. is there another way to get this loose. i sprayed it with lubricant, no difference. some advice that doesn't say take to a shop, because i will soon but i know that i can do this. thank you
