My mower won't start and here's the situation and what I've tried so far. It has been running this spring even with a tankful of last summer's gas. But I wanted the blade sharpened and a service (spark plug and air filter check) so I took it to a free community fixit place and watched as the guy removed my air filter which was in pretty good shape with lots of white and just a bit of debris, but didn't see the filter when he replaced it.

He checked the spark plug and sprayed something in the carb and it started right up. I guess he sharpened the blade. Anyway, I came home and the mower ran for about 10 minutes and then stopped running! It wouldn't even turn over. I pulled the spark plug and I don't think it's the same because it's not the part number the manufacture suggested. I purchased a new spark plug. Still won't turn over.

Then I checked the air filter and the one in there now is about 5 years old and filthy dirty. I am not sure why that guy felt he needed to take my good one, but whatever. So I purchased a new air filter, but still nothing. So, is it possible that the mower ran on last summer's gas for a little over a tank then quit?

Also, I pulled the new spark plug and it smells like gas and is wet, does this mean that when the guy laid the mower on it's side to work on the blade that the gas and oil are now in the engine and it so, am I doomed? If not, should I remove the gas and start with fresh - obviously yes, but at this point will it matter? Thank for your help!

Drain the old gas and oil and put in new. Clean the carburetor too. Good luck. Sometimes free service is expensive

I have a Craftsman LT3000. It has been sitting since July. I cleaned the tank and changed the filter and replaced the gas. It will not start and stay running unless I hold my hand over the carburator.

When I move my hand away it dies. What can I do?

Hopefully you have found a "fix" for your mower - or - better yet - you have not needed it and can take your time finding a solution.

I have always found that I could get help/remedies for most of Sears products at their Sears Parts & Service departments.

If this information is still needed maybe you could check Google to see if there is a Sears parts store anywhere near you. You might get some help over the telephone but asking a question in person always seems to get a better response. Besides that, they have books (with pictures!) and that is always a help.

I did find a video on YouTube that may help and also a site to download a manual for your model (look before printing 27 pages).
Good luck with your mower.

Try changing out the spark plug and cleaning the old gas out of your carburetor. It sounds like you have some dirty gas in your engine that was left over from the last time you used the mower.

I own a 6.5 horsepower Craftsman lawnmower, model number 917.377662 which has a Briggs and Stratton 4-cycle engine. It won't start without using a starting fluid spray. I changed the air filter, fuel, spark plug, and serviced the carburator using a carburator kit, with the same results as before. I needed to use starting fluid. Suggestions? Thanks!

I haven't used my mower in about 2 months. I tried to start it today, no luck. I dumped the old gas out and cleaned the filter just like the internet said to do. I just purchased it in May of this year. What do I do?

Take back to store for replacement or at least get help to return to manufacturer. Most equipment has one year manufacturer's warranty against defects.

My Honda HGR 536 lawnmower is not starting. I have tried all the normal things, ie. change spark plug, checked the spark, and made sure it has enough fuel and oil. I also checked that the cut of fuel tap is in the correct position.

I have a Craftsman 6.5 HP self propelled mower. It is maybe 10yrs old and runs great once I get it started. I have the problem every week. I have to prime 15+ times, then pull the thing until my arm is about to fall off. I have had it serviced, oil, plug, carbkit, and the base air cleaner replaced. This one has the primer bulb. It is not bad gas, I drain and run it out every year. Once I have it started it will run and restart without an issue. A week later, same issue.

I have a Craftsman mower, model #917375622. I cleaned the carb and it starts for about 8 seconds then dies. It's fairly new, but I can't get it to keep running. It has a good plug and filter; choke works. What now? Should I try recleaning the carb again?
