Craftsman 7.0hp 21" Self Propelled Mower Stalls

I have a few years old 7.0hp Craftsman rear wheel self propelled variable speed lawn mower that stalls. It takes me about 10 min to get it started. As soon as I prime, pull the cord, it runs for a few seconds then stalls. If I prime it as it's about to stall it will run a little but stall eventually. It's been taken care of thru the years (change oil, plug, air filter every season). This started last year. This year I tried some additive in the fuel to clean the internal engine, but it stil does it. Any suggestions? I'm ready to set it by the side of the road.

Model numbers

OK it's called a 7.0hp Briggs & Stratton Quiet Power. 698831. There is also another set of numbers 28602 0304 E1 040323FA. It's an OHV. And it runs like crap. I'm ready to get a Honda. I just finished putting Sea Foam Motor treatment recommended by the local auto shop and it hasnt helped. It's supposed to clean injectors, carbs, frees lifters, etc. PLEASE ANY ONE HELP? If not, it'll be by my curb next week, come by and pick it up..

Clean carb, install new needle and seat PN# 398188 and clean main jet ( nut that holds the bowl on). Other than small amounts of seafoam fuel additives are unnessary if you service the carb regularly and use ---fresh-- fuel. After cleaning the carb do not take a chance of putting contaminated or stale fuel into it. Empty the gas tanik int yoi red can and empty your red can into your vehicle and get fresh gas from the pump. Your machine will aprreciate it

Claean Carb, needle?

OK thanks. I always use fresh gas from the station so I don;t think that is a concern. Also, my application of the Sea Foam additive has been over about 6 weeks using about 2 oz per week.
last questions, how do I locate and clean the carb and replace the needle? Is it relatively simple? I'm relatively handy but don't want to dissassemble the entire engine. Is is where the primer button is located? Any tips or instructions on the web?

Good news!!!

Sorry, it's taken so long. I actually tore into the carburator, replaced the parts I got in the overhaul kit and flushed it with carb cleaner a few weeks ago. I took pictures as I did it so I knew how the parts went back together. Anyway, I reassembled, put fresh gas in, primed it three times and it started right up and ran like new. It's been running great ever since. I am SO glad I decided to try and overhaul it and spend the $20 vs. throwing it out and buying a new one for over $400. Another reason to keep being a "do it your selfer"! thanks to all who gave advice.

A Follow Up ?

Hello all. I KNOW this is an old post but just wanting to check and see if anyone knows where to find the user guide for this mover. Mine is doing the same thing. The number off of the mover itself are Model number 917.378941. Now that is a Craftsman and all and they even have a number on it to call but I figure this is eaiser than to deal with all the drama on the phone.

Thanks,


Dan

You can go to the sears site and enter the model number for a breakdown, you might be able to get by with removing the carb bowl and cleaning it and the bowl nut(main jet). Have a good one. Geo
