What do you mean bump the starter exactly? This is mt first time completely redoing an engine, its on the engine stand and all stripped down, starter removed, but I cant get that bolt off.
By bump the starter I put a breaker bar & socket on the bolt with the edge of the bar on the cross member. Tap the starter & it will break that bolt loose. Its a PITA to do it on a stand. Another way to do it, might damage the piston is put a screwdriver in the spark plug hole to keep the motor from turning when you try to break that bolt loose.
If it's on a stand it's hard. Do not stick anything down the spark plug hole to jam the engine. You can usually get more torque with a breaker bar than an impact. Put two of the bolts into the crank on the back and put a pry bar across them and jam it up against the stand to keep the engine from turning. Like so: Green is pry bar, red is crank bolts. Then use a breaker bar with socket up front like normal and crank on it. Make sure you put the bolts into the crank a good bit. If you barelly catch the threads you may rip them out. -Ryan
Impact didn't work, so I am going to try Ryan's plan. Though I did the exact same thing and completely bent the screwdriver around the bolt I will try it with a pry bar like you suggested. So we shall see... Thanks all!
