There should be a drain plug on the underside of the mower deck. Raise that side of deck, remove the plug and drain the oil. Replace the plug and add new oil. Hope this helped.

SOURCE: briggs & stratton with idle problem

This is not unusual at idle; there is a governor to limit maximum RPMs and this device isn't worth beans at an idle.
You may be able to carefully adjust the idle adjustment (see your manual or B&S website) to achieve a somewhat more even idle speed.

SOURCE: craftsman 19.5 lawn tractor w/briggs & stratton keeps flooding

This could be a number or items from no spark to a faulty carburetor, a plugged up air filter, valves out of adjustment, poor gas, faulty spark plug.

First, see if your getting spark, how about taking the wire off a plug(s) and holding it about 1/8" or so away from the plug with some masking tape while you crank the engine. You should be able to see the spark jumping the gap, it helps if it is not too light outside. If you attempt to do this with your hands, you will get a spark jolt, it hurts, so use the tape and remember, the engine could start so proceed with caution.
If you have no spark there, then you ignition or magneto is faulty. This would be unlikely in the broader scope of things. You will likely get spark. Make sure the plug is clean, take it out and inspect. If it is covered in gunk well clean it. It will smell like raw gas but you already know that. Change the plug if in doubt.

Remove and clean and replace the air filter.

If you have spark, and a clean filter it is likely a carburetor problem, Depending on the carb, it could be the choke is faulty or, as per the below.

Depending on what model you have there is a float assembly in the carburetor that stops the fuel from flooding the carb and air intake. The gas tank is higher then the carb right, so if you dont have a mechanism for stopping the fuel from leaking out the hole that goes into the engine, it will all leak out right, as into the fresh air intake because its easier than going into the engine. So, there is a miniature float assembly, sort of like your bathroom toilet float to stop the water. Well there is a small wedge type needle that seats into a hole and it is attached to a float. As the gas rises in the bowl, it pushes up the float, sealing the gas into a chamber, as you use more gas, the float lowers and more gas goes in. So ,there is dirt jammed into the float bowl sealing needle, just a little, thats all it takes. So, shut off the gas somehow, hopefully you have a valve, or squeeze the rubber line, then undo the float chamber, its one nut on the bottom. Clean carefully. The needle, little spring and float assembly are delicate. Also, the needle could be worn from engine vibration, so it may need a new needle. It would help if you described the engine and carb though.

I posted that as a solution to another problem, but yours may also be the valves need adjusting. Depending on the amount of hours, say over 200, then the valves timing will likely be off a bit. Check the clearances with a feeler gauge, it is not as difficult as it seems. Check your Owners manual for the clearance at top dead center. TDC is when you take the plug out and watch the piston arrive at the top of the cylinder through the spark plug hole when you are turning the engine over (do this by hand, battery off. Make the adjustments with the valve cover off. Follow the instructions.

Hope some of this helps.

Do a compression check when cold, then again when hot. Sounds like when its hot your losing compression. If this is the case, it won't want to start when hot. Compression should be above 60 lbs. Thats where i would start. I hope this is of some help to you.

What are the torque specs on intake manifold on Briggs & stratton


if there is thread locking compound on bolt or threads it must be removed, use a tap to clean the threads and a wire brush to clean the bolts. Use a thread locking compound (blue) when reassembling, torque the bolts to 30 ft. lbs. alternating bolt to bolt in 7-10 lb. increments. Recheck the torque after the engine has been ran up to op temp.

Head bolt torque for 16hp horizonal shaft engine


Anywhere from 35 lbs to 220 lbs, depending on the series of your engine. For your engine, the head bolt torque should be 190 lbs.

But I've attached a chart for you to utilize to make sure of your exact engine model series, just in case there was a transposed number, etc.

http://www.small-engines.com/torque.html

Here's the official Briggs & Stratton chart for all versions of their engines, which confirms the 190 lbs torque spec.
