2166 stalls after it heats up

Hi John:
Have you checked the basic maintenance items?
- Air filter
- Fuel filter
- Fresh fuel
- Oil level
- Spark plug condition
- Clogged underside of cutting deck

Check that the blade brake is disengaging. Slip belt off blade spindles and check that they spin freely. Check underside of deck for clogged grass, ropes, wire, etc.

Try this:
As soon as the motor begins to stall, loosen the gas cap. If that helps, clear the vent holes on the cap.

I had a similar problem lasy year.
Try this:
As soon as the machine seems to be stalling, loosen the gas cap.
If the engine continues to run, clean the gas cap vent hole(s).

A common loss of power problem with B&S V twins is a set of crumpled valve push rods. Means you are running on one cylinder which is generally OK unless you also want to mow. Easy to check, pull one plug wire at a time off. If it continues to run on one cylinder but not the other, that is your dead cylinder. As the intake is not opening, there will not be a wet plug. Costs nothing to check and could be your problem.

Sounds like the float and needle need to be changed. The float is fluctuating too much causing the needle to raise out of the hole to the carb just enough to keep it running but not enough to stay running. Replace the needle and float. This is something a lot of people over look and most the time is the problem.

its likely to be a switch playing you up try hard wireing the switch to see if it stops this cutting out first, do one switch at a time till you fine the one playing up

Have you checked your air filter..it sounds like it could be dirty and needs replacing..if this dont help..just comment back and i will get it..and i will help you further..Keith

A FEW THINGS TO LOOK AT ARE ,1THE PULLY SHIELDSMAKE SURE THEY AREN'T BENT TO CLOSE TO THE PULLEY'S.2 THE PULLEY BEARING'S MAY BE WORE OUT AND TO BREAK .3LOOK UNDER THE DECK TO MAKE SURE YOU DIDN'T GET SOMETHING TRAPED IN THE CUTTING DECK.HOPE THIS HELPED.
