Briggs Stratton chipper stopped running Model 24A-464G129

Just had my chipper fixed - rope starter had come apart - and had oil changed and new spark plug put in. Been using it a lot, and went to use it two days ago and it started up but wouldn't run full power. Just sounded like it was barely staying run ing. I shut it off and checked the interior for a clogged stick but it was clear.

Now it wont start at all. A few times in the last week or so I had overloaded it and the engine almost turned off. I thought I saw sparks coming out the exhaust so I stopped for the day and let it cool. Started and ran fine the next day.

I didn't have any problems with it the last time I used it.

Air filter is clean. I have fixed the carb on my mower in the past when it wouldn't start. Could it be the carb?

I have used it about seven times since servicing....for about an hour and a half each time.

Could use some help...thanks!

Is the spark plug wet? Is it sparking? I would suspect water or trash in the carb just off the cuff.

 

Your going to have to do the basic engine debugging. Every engine needs; fuel, spark and compression. Compression is the most reliable and since the engine was running and you didn't report a sudden stoppage or awful sound I'd ignore it for now.

Probably the number one cause of engine trouble is dirty or old gas clogging or partially blocking a passage or orifice in the carburetor. A clear sign of carburetor problem is if the engine needs the choke to run.

You can check for spark by removing the spark plug and let it's body lay on bare metal of the engine. Pull the starter cord and you should see the plug spark.

 

I think I found the problem...

I'm a newbie, so go easy on me, but what exactly am I looking at here? That rod shouldn't be there, attached to nothing. The top two pictures uploaded sideways.

 

Yes, a bent pushrod. It's probably not what went wrong though... it likely bent because the valve stuck. Hopefully you still have full travel of the valve and the guide didn't move. Burning old gas is usually what causes the valve to stick.
