Question about Garden

2 Answers

My 14hp 42" craftsman lawn tractor will initially crank over and run for a few seconds then it quits. the only way I can keep it running is if I completely choke the carb by putting my hand over the intake. and then it runs real rough and has no power. I think its getting too much air and not enough fuel. any suggestions?

Sounds very much like a blocked main jet.
Pull the bottom of the carby while holding your hand cupped under it.(turn fuel off first)
If you find water drops, that is your problem.

If not,
Find the main jet.
Usually brass and in the center.
Look straight up into the carby and unscrew it with a smallish flat blade screwdriver.
Hold it up to the sun, you should be able to see a nice clean little hole.
If it is blocked, clean it with a wire from a wirebrush. Be gentle, if you damage it, you will never get it to run nice.
Clean every part carefully before re assembly.
Turn the fuel on and mow, mow, mow. :)

Won't start after killing the motor


May need more info. Check for a seat switch to have came unpluged (wiring) this is a safty thing. You have to have your foot on the brake as you sit in the seat to get it to crank. repost if you need more help.

Craftsman 19.5 riding mower starts runs quits no power


When you let it sit did you remove all the fuel or add a additive? If you did not then I would recommend that you remove all the fuel and add brand new fuel to your system. Gasoline only last for about 3 to 4 months before it will start to go bad and this sounds like your problem

Starts quits then starts after a few min


Have you checked your fuel filter? it may be clogged or contain water, which will limit flow of the fuel. This would be simplest to relace. Otherwise I believe it to be a carb problem.
