ive got a lesco 54 inch rider with a weird fuel problem.it will run just fine wide open with blades off turn blades on and it putters in and out and sometimes tries to die kill blades runs fine again.thought water could be in gas bc thats how it acts cuttin in and out put some stuff in gas doesnt matter still does it.also if your mowing on a hillside and blowin grass uphill runs fine when turn around and blow grass down hill wont run at all.flat ground will cut in and out some but not as bad.took the carb off to see if some water was in fuel bowl and didnt look like it.mower does need plugs and im puttin new ones in tomorrow but whats weird it will run all day long just fine with blades off.anyone have a clue what to check its driving me crazy

I have a Lazer, had the same problem, any time there was a load put on the engine, such as the blades being put on it cut out....i took the carb apart and unhooked the fuel line and blew it out with my air compressor...it's happened twice and that fixed it both times, apparantly a small piece of trash/debris got in there....hope this helps..oh and not to mention changed the air filter inner and outer elements, or at least blow yours out a little depending on how old they are....

You may have a leak in an intake gasket or fuel line, also. It sounds like it my be sucking air from some point.

had the same thing happen w/ my gravely two days ago. changed the fuel filter, cleaned the carb and it was fine. everytime i tried to engage the blades, it just died out. but it ran fine in neutral w/o blades engaged

Right on grassisgreener on the fuel filter change, i forgot that!!

Carburetors are very susceptible to fuel contamination; the smallest particle will render it inoperable.

Oh well, this not being in the Mechanics and Repairs Section, sorry I can't help.

Try running seafoam in the gas...pour the whole bottle in there

If you hear any noise when you engauge the blades..you might have a spindle locking up and that too will pull motor down to point of almost killing. but you most likely hear a noise. But it sounds more like mentioned..fuel problem when on demand.

Try a new fuel filter!
