Remove cylinder head,
Remove valve side cover,
Remove valve springs to free valves,
Measure gap between end of valve and cam follower, while pushing valve onto seat with finger,
To make gap larger, pull valve out and grind some metal from end with bench grinder, (carefull here),
When gap is correct and valve seats without turning under finger,
Reassemble.
Look under dash in right side.
if you mean valve clearance its .26mm intake side and .30mm exhaust side
Few Briggs engines use valve seals and those use them on the stem of the valve, sometimes only on the intake side, to prevent oil blowby. If you refer to the seats that the face of the valve seals against, then the answer is not usually. Older engines(valve-in-block) have part numbers for them but it is an arduous task to get them to stay in the block. They are usually just cut and resurfaced and the valve is either replaced or cut. They are then set to the proper clearance by grinding the length of the stem.Newer OHV engines simply have the head(s) replaced as needed and the valves installed and adjusted.
valve clearance should be pusted under tune up spec under "stock hood" sticker should be on the left hand side
They are on the inside of the hood. Mine was on the left hand side.
I just put mine to stock which is .004in on the intake side and .005 on the exhaust
There is no way to adjust the timing on a 17.5 Briggs engine. The magnet is on the side of the flywheel and there is only one way the flywheel can line up. All you can do is make wure that the coil is gapped correctly.
there should be a screw in the side of the carbuerator. turn the screw all the way in be careful not to bottom it out tight you will ruin the needle valve. then turn the screw opposite 1 1/4 times this should be good slow idle and also fast idle speed.
i just take the cap off and tip them to the side into a drain pan, most of them have a plug on the bottom, but easier through the fill tube
it has a divided diaphragm inside and one side sucks gas from the gas tank and the other side sends gas to the carb. And I think the hose that goes to the decompression aparatis is where it gets its air/suction
It could be that the mixture is a little on the rich side. Close (rotate clockwise) the needle valve on the carburetor about 1/8 of a turn.
Hi, Most engines have a dipstick and tube and it can be drained by placing a suitable container beneath it with mower turned so the tube is on the downward side of the engine.
