Question and Answers

Q:

engine speed varies irregularly 917.254641

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having with the irregular speed of the tractor. I know how frustrating that is.

This sounds like a surging issue. This is almost always caused by an internal blockage inside of the carburetor. The carburetor will likely need a thorough cleaning, rebuild, or replacement depending on how varnished it is. I would start with a cleaning first to see if that solves the issue.

I would pull the carb from the engine. With a full can of carb cleaner, a wire brush, and a bread tie wire to poke through and clean the main jet; I would recommend a very thorough cleaning. Start by taking off the float bowl. Douse it very liberally with carb cleaner, and undo the pin for the float, and remove the needle and float. Clean them very thoroughly with the wire brush and carb cleaner. Pay close attention to the seat the needle sits in and clean it well. Once clean, start brushing the carb bowl and body and make sure you get all the varnish out. It may take three or four brushings with carb cleaner dousing in-between. From there, take the straw of the carb cleaner and shoot carb cleaner through any little hole or passageway of the carb. Shoot out the throat of the carb and poke the main jet with the bread tie wire. You have to make sure you get everything the first time, if you leave anything behind, it’s likely to reclog once you have it reassembled.

Q:

engine stalls when engaging mower lever 917254641 Craftsman 12 h.p. 38" riding lawn tractor

A:

I am sorry to hear of the issue you're having with the tractor stalling when engaging or trying to engage the mower deck. I know how frustrating that is.
The most likely cause to this issue is a defective switch in the safety circuit. It could be either one of the interlock switches or the seat switch. It could also be that the seat switch connector contacts are dirty, or the seat switch connector is not firmly pressed onto the seat switch. 
I would start by undoing the connection to the seat switch, clean the contacts, and press it firmly to the switch when clean. If that doesn't work, you will need a multi meter to check for continuity on the three switches to verify which is defective. 
To help you, I have attached a YouTube video below that you can watch on how to test the switch for continuity.
