I just picked up a ride on with a 40777 22hp B&S Intek engine. I was told the starter was bad so I replaced it with one I had. put a battery in and it spun. I put fuel in the tank (previous owner drained it before storing which was nice) and tried to start it. The PO mentioned that he always has to pour some gas in the carb to get it started.
well, I could not get it started so I poured just a little bit in the carb and low and behold it started.
I shut it off and tried to start it again and it wouldn’t, I moved the throttle F to S a few time thinking it might prime it, tried to start it in choke. Still nothing. A little gas and it turned right over.
How does the primer work on these, is there anything I can do to get it to start on its own?
I doubt very much there is a primer on this engine. Are you sure the choke butterfly is completely closed when putting the control in the choke position?
If you just picked it up and found this problem, I’m guessing you have a carb that is probably gummed up with old fuel being allowed to sit in the carb.
Owner told me about it. He had been doing it for a while. He had a little thing rigged up to do it quicker than pulling the air cleaner off. (It has 4 thumb screws)
It is amazing the work arounds we see for simple thigs like backing off the cable clamp and moving the cable 1/8" so the choke closes fully.
Bush mechanics ( redneck to some ) is fine to get you through the day but rarely a long term fix.
What is the complete model, type, code of your Briggs?
This info is usually on the top of the valve cover if that is a OHV Intek.
Sometimes someone will install a valve cover upside down and the info cannot be seen.

It's rare I can clean a carburator good enough to correct an issue like this - usually just change it out with a new one - most are under 20 bux on Amazon - I have installed a primer bulb on machines that previously didn't have one to overcome this type of problem although usually they will start up fine after the initial startup. Yours sounds like a fuel supply issue maybe a fuel pump that is not up to par or a dirty filter etc.
What bertsmobile1 indicates above is quite common on those single cylinder OHV's if the throttle control cable is not clamped properly at the throttle plate on the engine.
You can look/examine at the choke operation of the carb choke linkage if you remove the breather assembly and then move the throttle control on the dash back and forth. At full throttle the choke butterfly on the carb should be closed if the throttle cable is located properly in the clamp and the choke's plastic lever on top of the carb is not broken, etc. (if someone has cut off the length of the throttle cable too short the choke will not get full travel)
Some of them engines even requires a choke for a quick warm start.
Bush mechanic's Bubba and Clyde probably gave it a tune up previously.
