Hey! I’m new here and have run into an issue with a couple of mowers with the same Briggs and Stratton 190 cc auto choke system that I just can’t seem to solve. One is a Husqvarna, the other a John Deere (just got it today, wasn’t working.)
I’ll start with the Husqvarna. I received it in a trade, it’s an awd mower in really nice shape. I ended up getting it to start and it ran great. Then after letting it sit for a while, for some reason it wouldn’t restart. To make a long story short, I pretty much changed everything out (carb, auto choke parts, spark plug) and still, same problem. I noticed that when it would do this, the choke was shut. My dad suggested to hold the choke open while he tried to start it, and it did the trick. So I ordered a brand new thermostat to see if this might cure the problem, and still! After letting the engine cool down for about 20 minutes after use, would not start unless we helped it by opening the choke...
So with the John Deere mower, (again I’ll shorten the story here) it would struggle to stay running unless I kept it on full choke. After cleaning the carburetor (it is brand new) a couple of times, checking the auto choke parts, I ended up finding out the intake manifold had a big crack underneath it. After swapping it out, it started up and ran perfect! However, after about 20 minutes I went to start it and it wouldn’t go (ughhh). It reminded me of the Husq, so I checked the Choke (it was shut), opened it, my dad gave it a pull and it started right up no problem!
So I’m stumped on this. I’ve had many of these mowers, repaired many of these kinds of mowers, and these are the only two that have given me this problem. Has anybody else ran into this problem? Am I missing something? Also wanted to add that after getting it started and letting it warm up a bit, it’ll have no problem restarting unless I let it sit for another 20 minutes or so.
