Troybuilt mower and weedeater

The Troybuilt mower is a 190cc engine self propelled just over 1 year old. It starts and runs, but runs on like very low power. Sounds quieter than my weedeater. As soon as you put in on already mowed grass it bogs down and dies. I have put fresh gas in, changed the spark plug and changed the air filter. Any ideas??

The Troybuilt weedeater is just over a year old and starts and runs for a little while then starts sputtering and then dies. I have replaced the gas with fresh gas, changed the spark plug and air filter. What next??

Thanks so much for input!!

I suspect something has clogged a jet or small passage in the carbs. Fresh gas, new spark plug and air filter will not remedy the problem. The carbs. will have to be disassembled and cleaned.

One at a time or put them in separate posts, it gets very confusing. For the mower, post the engine mfg, model type codes etc, so we know what to look for, it could have a honda, briggs, tecumseh, subaru, etc. Have a good one. Geo

Sorry for the delay in responding.
The mower does not have a model number that I can find. It is a Briggs and Stratton 190cc engine. It revs up then goes almost quiet, then revs up and goes almost quiet, then revs up, etc.....

I will make a new post for the weedeater so it is seperate.

Thanks so much for all help!!

The model, type and code is usually stamped in the metal shroud by the spark plug, i will guess it has the plastic carb setting one the fuel tank, if so the following instructions should get you going, if it is a different model, this won't work.
You need to install a new diaphram kit, it is Briggs part # 795083 or old # 495770 also Lowe's has a kit #5083 which has the same parts.
Here we go;

Remove air cleaner, there are 2 bolts that hold things together, one on the front of the tank 3/8" and one into the block 1/2", remove these bolts, now "slowly" slide the carb/tank off the intake tube and breather tube, now tilt the tank in to release the throttle linkage and waalaa the carb/tank is removed. Check the intake tube to see if the O ring seal and plastic retainer are still on the intake tube, if so remove them and re-install them into the carb. Remove the 5 screws from the carb/tank remove carb(don't loose the spring) now spray all holes, cracks and crevases in both the carb and tank surface with brake parts cleaner, remove the main screen(looks like a thimble), now with a small screwdriver pry out the main jet(carefully) and clean it, check the O ring on the main jet for damage, if it is damaged it must be replaced, reinstall the jet, it can be difficult some times to get it to snap back in place(I use the rounded end of a screwdriver handle). Remove and clean the fuel pickup stem(not necessary if the fuel tank was clean). Clean any junk/rust from the tank. Install the diaphram on the tank then the gasket(no goo or sealer) now carefully replace the carb(the spring will try to misalign the diaphram), tighten all screws a little at a time so as not to crimp the diaphram until they are all tight. Install the carb/tank in reverse order and you are done. If I missed something one of the real mechanics will correct me. Have a good one. Geo
