11 hp briggs engine does not want to run, floods
Original Message Aug 23, 2009 9:37 pm

I have been working to get an leaf loader ready for fall clean up. The 11hp briggs and stratton engine starts briefly when choked and then dies. Gas runs out and drips below. It runs all of 3 seconds before it dies. I've tried starting it without the choke but no luck there. When I bought it a week ago the previous owner started it on the first pull. It has a good spark, fresh gas, a clean air filter. With the spark plug pulled I can see the spark. I've tried starting it at half throttle, full throttle and low throttle. No difference there. I took the bowl off the carburetor and cleaned out the crud that was in there. Do I need to take the carb off and completely clean it? What setting should the throttle be at for start up? Any suggestions? the motor is a Briggs Industrial Plus model 256422 type 1015 -E1

Runs like a top. I got it back together last night and started it this morning. No hesitation, idles smooth and quite, revs right up there, sucked the leaves off the driveway. It must have been that bad crankcase sensor. Maybe it got jossled around on the trip home and knocked out of position like friiy alluded to. (That's a new one for me). The leaking fuel pump was a real distraction in diagnosing this. And the fact that it would start for a few seconds and then die? Very odd. I was planning on leaving the oil sensor disconnected but if its worth my time to fix I will.

Thanks for all the help and patience. I couldn't have done it without you (no exageration there). I am ready for fall. Bring on those leaves!

You can put a Ohm meter to the float assy and check to see if fails on the float or if the problem is in the switch. It could be a bad wire bumpign into something and grounding the unit out.. You could get a new gasket so next time you change oil you can pull the float out and wash it out in some gas.. (the oil alert/ Guard unit is encased in a tube and has holes that let oil in. sometimes muck or sludge hamper's its movement inside) &amp;amp;amp;lt;BR&amp;amp;amp;gt;&amp;amp;amp;lt;BR&amp;amp;amp;gt; Just keep a good eye on your oil till you get it working...&amp;amp;amp;lt;BR&amp;amp;amp;gt;&amp;amp;amp;lt;BR&amp;amp;amp;gt; Maybe now you can till the leaves into you garden..&amp;amp;amp;lt;BR&amp;amp;amp;gt;&amp;amp;amp;lt;BR&amp;amp;amp;gt;&amp;amp;amp;lt;BR&amp;amp;amp;gt;Friiy&amp;amp;lt;BR&amp;amp;gt;

I never thought to try an ohm meter. I have one of those. So to check the switch I would disconnect the wire at the sensor's post on the outside of the engine block and then touch one lead from the meter to the post and one lead to the engine block? And if oil is full in the engine, the meter should show no continity, but if the oil sensor is showing &amp;amp;amp;quot;low&amp;amp;amp;quot; (or faulty in this case) I should detect continuity? Is that about right? ;And then if the oil sensor checks out OK then I should test the wire and see if it's grounding out someplace. &amp;amp;lt;BR&amp;amp;gt;Yes, you read my mind with the leaves being tilled into the garden.
