toro time master won't restart when hot?

[The motor guy]

It's like it loses compression and the recoil becomes easy to pull, so it won't restart unless you pull it really fast vs on a cold start you can pull it fairly gently and it pops right off. Pulls my stomach muscle when when I pull that cord too hard. End up being sore the rest of the day. it's got like 500hrs on it now, so I don't know if it's worn out or if maybe a simple spark plug would solve the problem. I haven't changed the plug in it yet.

Check valve clearance. Common problem with your symptoms.

Change the Spark Plug, 500 hours then check your Valve Clearance. These small mowers do not like to restart when it is hot. I run mine the whole time. If I need a bathroom break, I just keep it running.

Not normal. It should restart if all is well.

It's not hot outside yet though. It wasn't an issue before.This happens on my 2 strokes. Won't restart when hot, so a new plug fixes it typically. Never had the issue on a 4 stroke though

In addition to the valve clearance, it's not uncommon for a coil to get weak or fail when hot.

Consider it could be overheating. Take the top cover off to check for grass, mouse nests, etc. obstructing the cooling air.

Sounds like the exhaust valve is riding on the cams base circle when it's hot.

Pretty much everyone ignores valve lash.

I thought the lifespan for these residential engines was 500hrs though. Probably just worn out, but I'll check. It's a pain to get the old gasket off. Though. I guess I can use a wire wheel on it.

You were given several good things to check but you sound like you really just want to replace it.. so why ask? This is a tech heavy message board, you had to know that you were going to get more ideas than change the plug or replace it.

Where did I say I was going to buy a new one? I said I was going to check the valve lash. I'm just not looking forward to scraping the old gasket off the valve cover.

Be nice now.

The handle broke in half on this thing now the other day.

The mower handle or the pull starter on the engine?

mower handle. Those dumb two piece foldable handles are junk. Guess I can just weld what's left to the other part

 

[The motor guy]

I pulled the valve cover off today and the flat round piece that goes between the valve stem and the rocker arm was just laying at the bottom of the valve cover. Guess they were loose enough for that to pop off. Lol I think that's called the valve stem keeper.

 

[oilcandave]

While yer replacing the keeper might as well replace the spring as another poster recommended..

I'm trying to find the specs and I can't remember which is intake and exhaust. Looks like the valve next to the muffler would be the exhaust. I'm not as dumb as I sound, I only do this about once every 5 years, so I have to remind myself

 

[The motor guy]

Okay, so the push rod isn't doing anything on the intake valve. I tried putting it at top dead center and there isn't any movement. What does that mean? Probably the camshaft. I wonder if this engine has plastic cam lobes. Briggs 223cc vertical shaft engine. What a pos

Just buy a Command Pro 224 and be done with it. My Briggs 223 isn't even broken in but down the road that's my plan.
