I've a one year old Simplicity Courier with this engine. When the weather's above 50 degrees it starts easily. Once below that it won't unless cranked for minutes at a time. Obviously the "ReadyStart" feature doesn't. I can't get any information on what to look at or adjust from either B&S or Simplicity other than "take it to a warranty center", and that's not an option. Other than replacing the whole engine with something else, what can I do? Any ideas?

Has done this since new. Purchased in Nov. last year, but only tried running it a few times before putting it away for the winter. Always had difficulties starting in cold weather. We're listing our home in Feb. so I've been trying to keep leaves & stuff cleaned up (have a Swisher lawn vac). I've started taking the air cleaner cover off and putting a squirt of fuel on the cleaner itself. After putting the cover back on it'll start within a second. I'm positive the ReadyStart ins not closing the choke correctly and am not interested in having to haul it off to a dealer, especially my closest one (I've very bad history with them!). This should be something simple to fix.

There isn't a "model number" on the engine tag. It has "Engine Family: HBSXS.7242VE" Manufactured in 2017.

Most likely the model number that we are waiting on may be located on the valve cover opposite the one with the fuel pump.

There's an 800 number on one of those tags. Call them and ask where to find the model number.

Sure looks grubby and rusty for no older than it is.

That's the number for Simplicity (owned by B&S, but not the maker of the engine). It's called dust and dirt & not rust. I just don't wash & wax it enough . .

Tried calling the number and can't get through. Will look at the valve covers,

OK, there are no numbers on the valve covers nor stickers nearby (unless on the bottom side of them?). Here are photos from all angles. By the by, the dust shows up strongly because I'm using flash. It IS dusty, but looks worse in these than in real life.DSCN0010.JPGDSCN0011.JPGDSCN0012.JPGDSCN0013.JPGDSCN0014.JPGDSCN0015.JPG

On a whim, I used my phone to read the code on that one label, which led me to a B&S website AND said that the model number is: 44U777-0003-G1! Does anyone have an idea as to why they did it this way???? Anyway, that's the model number.

The model, type, and code numbers are stamped into the left valve cover. It is visible in two of your pictures, but can't read it. Didn't find any reference to the ready start in the corresponding service manual for your engine though.

Has thermostat choke system instead of a fully manually operated choke. Choke is still partially controlled by the control bracket. This set is reference on page 4/5 of the IPL along the control assembly and link on page 16/17.

BTW ILENGINE if you are a Briggs MST you should have access to the Power Portal which you could have easily found out the model number using the serial number. Also you won't find any thing on the Ready Start in the service because Briggs has failed to update their service manuals with this info. Otherwords the techs are let to figure this out ourselves.

waltben Most likely all you got to do is adjust the throttle cable at the control assembly. Put the throttle in the choke position. loosen the cable at the control assembly and either pull or push depending switch setup you have until the choke is fully closed.

No I am not stumped
It has also been a week since I asked you to check the valve lash.
When you come back with the answer to that then I will post a reply

I agree. Looked at the owners manual for the engine and it states for starting below 32 degrees move the combination choke throttle control to the choke position. Cable needs adjusted so the choke will close.
