ive seen many of these with the small passage in the fuel bowl nut
clogged. you can take the nut off and use a needle or a tag wire to run
thru it and then blow it out.

To repeat, it is a B&S Quattro, 4 hp.

I could find no fuel bowl nut.

this is also a good time to take the fuel
bowl off and was it out.

Fuel bowl is part of the gas tank. Can't take it off.
But I cleaned it out. Wasn't very dirty, minimal residue only.

if you still have a problem after this. i
would snug up the head bolts, check the flywheel key to see if its
partially sheared. there is a oring that goes on between the engine and
the carb that may be worn,, or the tube that the oring goes on may be
worn ,and a gasket on the other end of that tube that may have blew.its
easy to check the intake tube while your checking flywheel key. .....
another common problem is the valve clearance closes up so the valves
dont shut as well. you can use a file between the lifter and valve stem
to get the clearance back where it should be..006 intake,,,.011 ex.at
top dead center.. lucas.

Head bolts were tight.

It fouls spark plugs. Gotta be a fuel/air mixture problem.
Carb/tank is all clean, no apparent problem. Compression
feels a little weak.

Still don't know what the problem is ...

Why do I see so many B&S mowers sitting in the alley
waiting for the trashman? They are made to be lo-price.
To my knowledge, "They Ain't Much Designed To Be Worked
On".

Thanks,
