And it's barely doing that now. But once started goes good. That little red rubber bulb to suck up fuel doesn't work so I don't know if that's the function I'm replacing with the car cleaner. I wluod doubt it as it's now getting very difficult to start it even this way particularly when it's warm it seems like after it's been running.

If you think indeed I need that primer piece then is there a cheap way to get one on it's own anyone know of? Or maybe I should try some sort of gasket fixing goop I think I have somewhere. What ya'll think?

Otherwise what should I check? Thanks

Yes that is the function of it, to push some gas in carb for starting only.

Remove air filter, place your hand over carb opening, try to start, the second it begins starting remove hand.. If it then runs good, Yes the primer bulb "Sounds" like it needs replaced. you can look on Partstree.com, but you will need model # & serial # too.

Do NOT mow or anything without any air filter. This is test only..

Lol my arms aren't that long. You think this is electric start? Maybe stuff some cotton on there or something?

Duh, have someone help you & don't put anything on the carb, it will get sucked in then rope is pulled.

They're great little buddies who take care of themselves, hunt the local rodents lowering their grocery bill but sure no help around the house or in the yard

Ours are inside only cats.. So scooping the litter box is biggest thing, which isn't big deal at all.
Our oldest is 14, & the other 2 are brothers @ age 3.. All rescue animals, that's only way we roll.

Nice

Okay, never changed out the primer bulb as it kept working, with carb cleaner spray as usual, but now, starting yesterday after almost finishing mowing the lawn it won't stay started. I gets going for about 2 seconds then dies.

So what's this mean? Means I have spark but is the fuel just not keeping up? How do you check for that? I did take the carb out and stuck a wire wherever I could, which was only really in the main jet from under the float bowl and then under the valve in there under the plug whatever it's called but doesn't go anywhere.

What do I check from here?

The spark plug looks the same as usual, just kinda dry.

Please post the serial number for the mower and all Briggs engine numbers.

You have either a 124T02-0161-B1 or 126T02-0139-B1 engine.

Clean the carburetor including the fuel bowl nut/jet assembly.

Now getting the primer to will probably take so doing as the primer/air cleaner base is probably warped. Here I use a cuple gaskets to make a wedge to place additional pressure on gasket in the area of non contact. It is either that or a new primer/air cleaner base.

is it engraved somewhere on the engine? mine is so dirty, I'm gonna go by the manufacturer details on toro website that says Champion RJ19LM, same as briggs stratton?


The serial number is within the range stated there.

But anyway, currently it's running. I think it's being temperamental. IDK. But it was quite cold this morning, now it's a bit warmer and it got running. Though I'll take any tips as to why it requires carb cleaner to get started

also it struggles to start hot, like if I kill it on accident in middle of a mow, getting back going with carb spray isn't as easy as when fresh starting it. Very "temperamental"

Sorry, I couldn't understand what you said or tried to say in the last paragraph. Maybe there are some typos. first of all, are you suggesting that the busted primer bulb couid be affecting normal operation? Like it could be allowing excessive air flow or something?

If you can’t take the time to clean the engine, to find the engine numbers and you don’t understand what Star is trying to tell you; trying to be a DIY guy and fixing this on your own will probably cost you more than it is worth. Sorry to be brutally honest, but I have to call it like I see them

What Star is trying to say is these engines are known for the rectangular air cleaner base warping which allows an air leak between the carb & the air cleaner
The air leak renders the primer useless so some of us double the gasket
He sands his back in a taper so the double gasket is a wedge shape to compensate for the warped cover

And for hot start problems it can be a valve clearance issue.

Oh okay thanks. Gotcha.

But would an air leak in that bulb channel affect normal operation of the mower? At this point my main issue is hard start, well NO start without carb cleaner. Carb is newish, aftermarket. Got it earlier this year and just cleaned it up a little from underneath but don't know I really did much. Poked where I could with wire.

I thought the website was sufficient.

Would that also possibly contribute to hard cold start?

Have you any idea of how many times people have posted the wrong website? As techs we want to be sure we are giving good info on the correct engine, so we look up equipment before giving advice. Guessing is a last resort, plus being able to give us numbers tells us about the ability of the poster. In my opinion if they can’t find numbers, they probably shouldn’t be fixing.
