My craftsman lawn tractor turns over fine but won't start until after many attempts. It starts when I begin to smell gas. I've already changed the spark plug but that didn't help. The battery is new. Once it starts and warms up, it will start with the first turn of the key. This just started happening a couple of weeks ago. Thank you.
Had same problem with YTS4000. With throttle forward to start, check that the choke is fully closed. If not, loosen cable clamp that secures the throttle cable and slide cable housing till choke is applied . Retighten the screw that holds cable housing & turn key. Should start ok now. Hope this saves you a few bucks in service fees. PS// watch linkage movement while pushing throttle forward for indication to adjust choke application.
Testimonial: "Thanks to all for your input. I think it is a matter of adjusting the valves. I installed an inline gas shut off valve and changed the oil and it starts up first time every time now."
Change to a lighter weight oil for the colder months. Did you notice how thick 30 wt oil pours when temps drop? When it thickens like that, there is resistance when the stater has to rotate the crankshaft during the initial start. Once the engine warms, the oil thins allowing for easy restart.

Most likely needs valves adjusted. If you can give model number off of the engine, i can try to find the manual or instructions on how to do this for you.

Does the motor even turn over. Have you checked the carb. for gunk or gas trash.

does it turn over slow or fast if it turns slowly thats the problem so it could be battery or starter they have to have a good amount of rpms to burn fuel right when starting if not it floods out the engine with gas hope this helps thanks wade

I had a similar problem and found that the float was hanging up on the wall of the carb fuel chamber. I sanded lightly the outer edge of the float and never had the problem again. That was 3 years ago. Having a different problem now. After setting overnight in cold weather, 20's, engine turns over very slowly even with a new battery. Engine starts, but barely. Once running, everything seems fine. After shutoff, engine restarts quickly. Next morning, same thing happens. Anyone have any thoughts?
