Question about Briggs & Stratton Briggs Stratton Intek V - Twin Vertical Ohv Engine with Electric Start 22 Hp, 1" X 3 5/32" Shaft, ModelNo. 44K777 - 0027 - E1

There may be safety switches, but if you are getting a spark, that is not the problem. After you cranked with no start, is the spark plug wet with gas? can you smell gas in the cylinder after pulling the plug? It could be that your carb float/needle valve are stuck closed. Try lightly tapping the side or the carb.

The white smoke may have been caused by having water in the fuel, or fuel tank [due to condensation or exposure to rain and snow]. It may have been that the mower got tipped for cleaning purposes, blade inspection, etc. and oil from the low lying oil pan got into the piston.
Either way, I recommend installing a brand new spark plug and new gasoline [you can purchase a little gas siphoning hose for a dollar or so at any auto parts store] If you have gasoline left over in a can from last year it is safe to use it in your car as it mixes with lots of new gas, but not in your small mower tank as it is basically outdated fuel.

This same thing happens to me and I resolve it by taking the gas line off in front of the carb and blowing air through it.....then it will run fine. I realized I could do this when I took the air cleaner off and fed it gas manually and it ran fine....and I also had gas pumping through the fuel pump. I'm not sure of the problem....either the fuel pump is losing power or their is something blocking the carburator intermitantly

Hi and welcome to FixYa I am Kelly.
This post is listed under the Intek V-Twin engine that would be engine model number 281707-0148-01 so I am making my recommendations based on that model number. If your ENGINE model number is different from the one above please respond with the number.
It sure sounds like there may be a compression problem. All other elements
Fuel, Air and spark are in place. If you can not get even a backfire it sounds like there may be a valve sticking open. Probably more than one if not even one cylinder is firing.
I have one question..... Has this engine been sitting unused for a while?
Lets start with something simple. (again based on 2 cyl engine but procedure would be the same for a single cylinder)
1. Remove both spark plugs
2. Spray a very generous amount of WD 40 in BOTH spark plug holes.
3. Use the starter and turn the engine through for about 5 seconds
4. Again spray WD 40 into the cylinder head via the spark plug holes and let it soak for about 15 minutes.
5. Turn the engine through again with the starter for at least 15 seconds. Pause 1 min and then another 15 seconds.
6. With assistance Use your thumb to cover the spark plug hole opening and check each cylinder for compression
Compression = Yes / Install spark plugs and try starting.
Compression NO ... If engine is OHV remove valve cover cap(s) and spray WD 40 through the valve springs onto the valve stems then let them soak for about 15 minutes.
Turn the engine through again
Flat head engine
Remove cylinder head only and check the valve seats for coking in the seats. ESPECIALLY the exhaust valve. There should be a visual ring where the valve mates to the valve seat. If you can not see a visual ring then the valve seats should be hand lapped with valve grinding compound. (Valve Spring will have to be disconnected but NOT removed to hand lap with valves grinding compound)
Once you get a ring that you notice on the valves then reconnect the springs and install the head.
Check for compression with your thumb by having the engine turned through.
You really should have compression at this point.
Install spark plug and start the engine.
If you need more assistance or.. have a different model number other than the one above... then just respond here and some one will help you.
Thanks for using FixYa.

from briggs site:
For optimum performance, you should change the oil in your small engine after the first five hours of use and then annually, or every 50 hours of use (whichever comes first).
