Troy built lawn mower (riding) won't go full

This may sound screwy and you all think I'm probably a bit crazy but I have a Troy-Bilt 5550 generator model 01919 and it runs but surges. I also have a Troy-Bilt riding lawn mower which was doing the same thing, when I investigated it, it turned out that my gas tank on my lawn mower had those little "pincher bugs" that I got in my gas tank and was clogging the fuel outlet inside the tank I'm going to check my generator as soon as it cools down this evening as right now it's over 90° outside here in East Tennessee, and see if this is the same issue. Just thought I'd throw that out there it might be crazy talk but can't hurt to check I guess?

YES SIR, it is a simple repair with a float inlet valve and seat installation.

not sure on the specific type, but most engines run between 4&7 thousands

does it crank over?did you leave the blades on?are you pushing on the brake pedal

Probably an engine problem.
Does it run at max rpm with mower deck disengaged?

check your belt might be off a pully or maby your spring is off

i have a troy bilt riding mower,i start the mower it only runs for 15 to 25 min's ,so i changed the coil to see if it would run long. but after a few minunts it stop again so i don't know if maybe it's my carb. what could it be.... help

That is a safety feature with a lot of engines, there is a reset somewhere, call your Troy built dealer and ask him, I'm sure he will help. I will be a simple fix.
