MTD Seat Switch

MTD model # 136B560B700 Bought in 97

Part # is 725-1441 replaced by 925-1441A Both are discontinued.

I'm not sure if this is even the problem. Running fine for 90 minutes then just died, let it sit a bit and it started right up. Cut 250' and it died like I turned the key off.

Parked in front of garage and it ran fine for 30 minutes at half throttle. I put in a new fuel filter but the old one looks okay to me. Gas seems to flow fine, fuel cap on or not.

I did try the seat switch and it seems to work as it should.

That's about all I can think of, what next?

Thanks

Next time it dies be ready and check for spark.

Kinda sounds like a classic coil going out symptom.

Thanks

They can go out like that. You might even find that when it quits and you check for spark, you will see spark. If so keep going until it quits again and keep checking for spark. You can also use another spark plug so as to not remove the one in the engine for testing. It can be frustrating to verify sometimes. Them electron Gremlins can be elusive.

Okay, thanks. Went out yesterday and the battery was dead as a tuna...not even a click. Meter showed 10 volts. Charged it for an hour with my 6 amp charger, not it clicks at least. Hopefully CarQuest has a new one on hand, I'll try that.

Could that be the problem even though it did re-start a few days ago when it died?

Good idea using a second spark plug to check with, wouldn't have thought of that.

Thanks
