Model = 70573B<br />Serial = J0015725<br />Starts up fine when cold. After 5 minutes of running, it just shuts off, like I turned off the key. No sputtering. It will restart after cooling down. It seems as though something heats up and causes a failure of some component. I just don't know which one. Also, when the starter is hot, it won't engage with the fly wheel. It just spins. Do I need a new starter, or can I fix this one?

Two things to check/do.<br /><br />1. Remove and clean the negative battery terminal on the engine block.<br /><br />2. LIGHTLY lubricate the starter shaft. You can do this by "walking", by hand, the pinion gear up the shaft by rotating it counterclockwise.<br /><br />It also would not hurt to disconnect and reconnect EVERY connection you can find, under the hood.<br /><br />Make sure the battery is DISCONNECTED for all those operations/checks.

Re: "75" Evin 70hp just quits

I have done all this and believe I have fixed the starter. However, I have doubts about having fixed the main problem of the engine quiting once it gets warm.<br /><br />Let me ask this. Does this engine have a temperature sensor/thermostat? Is it possible that the engine could get a bit warmer than it's supposed to and some sensor shuts the engine down before it causes damage?<br /><br />What about the ignition stator under the flywheel? Could that be the cause of my troubles?<br /><br />And, what does the power pack do? Might that be bad?<br /><br />Thanks for all your help!!
