Last fall my 4300 hst started with not wanting to start after working it all day then letting it set over night. After a bunch of searching I did some testing and found somewhere to try shorting the white wire going to your shutoff solenoid and it will force the plunger back in. I did and it worked, so it seemed my shutoff solenoid was fine and I just needed a thermistor.
It wasn't a big deal to short that wire once and a while so that's what I did, here a few weeks ago it got a lot worse and wouldn't start unless you shorted the white wire so I ordered a new thermistor.
It worked great and fired up every time but twice since I replaced it it won't start. It's a lot better than it was before replacing the thermistor, but still something isn't right, and if you short the white wire it fires up every time which is what has me puzzled.
The only other thing I can maybe think is my shutoff solenoid is getting weak, I might try pulling it off and cleaning it to see if that helps but figured I'd ask and see if anyone had any insight.
Thanks
