Late last year (2020), my neighbor threw out a very similar Craftsman 6.75HP self-propelled lawn mower. He put a sign on it which read "Doesn't run, take it for scrap." Well, I took it home and quikly determined the problem to be exactly what your video stated. I installed two gaskets on the carb. primed it and it fired right up.

Just did the same fix the other day with a mower that someone gave to my neighbor and he didnt want it. A nice craftsman front wheel drive. In a pinch if you dont have an extra gasket i have used a strip of black electrical tape across the bottom where the air vane is and it sealed perfect .

Sounds like you have a warped air filter housing which is preventing a good seal. Glad you got it figured out. Cheers

Ok. In my case the float bowl O Ring gasket was leaking air. I also added a thin layer of RTV where the paper gasket seals the air channel on both sides. Back in business! Thanks again!

Not enough air gets through the airbox into the small hole in the carburetor. There needs to be enough gas to receive the shot of air. Some people double up the gasket on the backside of the airbox. I just tape the bottom part where the groove is located that carries the air. Maybe remove the screen behind the primer bulb to get more airflow. One bloke recommends a heat gun to warp the plastic more to the carburetor to seal air leaks better. Maybe remove the primer bulb and just blow on it with a straw to get airflow. Doubling up the gasket on the bottom portion might help. I hesitate to add something that might move a bit and block that small hole.

The slightest damage to the base plate gasket to carb face will screw up priming pressure. Seal the passage up to the hole or soak the gasket pre install.

My corny solutions: I find that "warped" black primer base plate is often the issue. Step 1. Double up the gasket. If no go, I cut a base plate gasket out of aluminum foil and bond it directly (with spray adhesive or gasket sealant) to the reverse of the primer base plate. Helps.

ill tell you what it is,,,uits the same problem eveyr briggs and stratton has wiht this type of primer system its on the other side where the gasket is on the plate isnt sealing properly this is a design flaw by briggs and strattong and explains why they went out of business because they decided to go the shotty route and build sub par things instead of good quality designs...teh gasket on the other side isnt ocmpletely sealing that tube that push air through , the air is escaping and failing to prime...soemtimes those ridges on it get warped or worn down over time..if it was sealed properly it would start...this is briggs and stratton being in the business of selling parts rather than building quality lawnmowers,,, they made a bad plate so youre forced ot buy a new one in a coupld years...or fix it wiht soem creativity..i saw a vidoe on youtube a guy used seom tape and put it over the airway and then put the gasket on . i tried it and the one i have fired up... didnt work on the other one however..ive come across this nonsense over many briggs and strattong engines its rubbish...some peopel put 2 gasket son and it works some it doesnt just have to find what works..its a shitty design

@@gradyhernandez4699 for the priming issue, I need a bit more info. Is it a Briggs and Stratton engine like the one in the video? If so, did you try the trick in the video by doubling up the air filter housing gasket? The surging is a fuel issue, it's running too lean (not enough fuel being added by the carb). You said it's a new carb but is it the right one for the engine? Sometimes the chinese knock offs run lean straight out of the box. Did you drain the old gas before installing the new carb? These are the things I would check first

It may have an adjustment screw somewhere hidden on no the carb.i ordered some gaskets already. I like the Toro mowers personal pace.
