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

2 Answers

Engine runs ok until the blades are engaged, if I take the plug wire off the left side, it has no effect on the engine running.I changed plugs and checked the coil and wire, it has fire and compression. If I take the wire off the right side the engine dies. I did not check the carb, although the plug in the dead cyl shows some gas on it.

    I should have added that the engine still runs, but at about half power

Try to determine if the safety switch on the seat is closing or opening.
Does this happen when you are sitting on the seat and engage the blades?

You're ight, if you have gas and spark it should run, if the mixture is right.

Good luck on this one.

    If the plug shows gas in it that is not firing, it could be a bad plug wire, and less likely a pluig that is bad. Or the coil is bad, and not giving full high voltage to the plug through a possible good wire.

    Replace the plug and wire in the offending cylinder to determine if this is the problem (ignition problem).

    Good luck.

You may have a bent push rod. I had the same problem and started tearing the engine apart. When I took off the valve cover on the left side(sitting in the seat)the push rod was just laying there.

After I changed the blade my TB 554 edger won't start

you have flooded the motor..
remove the spark plug.. lay it aside.. pull the rope until you can't pull any more (you are trying to "clear/clean out" the engine) ... You may have fouled the spark plug too... take your old plug and go to Wal-mart..or the local parts store.. get a new one.. and it should run.

Runs fine when blades not engaged, engaging blades causes engine speed to be reduced. Engine speed increases to normal when blades not engaged, or when motor not moving. Sounds as if mowing through very...

If it has a B&S engine, and many do, try this. Remove one spark plug at a time and start the engine. If it runs with one plug, but not the other, then you have a dead cylinder. That is why it seems to run OK so long as no load is on it.

I have had 2 different mowers with B&S engines which bent the valve push rods on the left (as the driver sits) side of the engine causing the problem you speak of. And if you google this issue you will find that I am not the only person who ever had this scenario.

If you have the OHV type engine you can pull off the little valve cover, next to the spark plug, and see the rocker arms and the push rods behind them. Replacing them is about as easy as it looks, however setting the gap between the top of the valve and the rocker is best left to someone who knows what they are doing.

My LGT 2554 Husgvarna mower engine tends to die when the mower blades are engaged. When the engine runs with the blades off at low idle it is ok. When you advance the throttle fast to full it loses power...

A common problem on the 21 & 23HP models is bent valve push rods on one cylinder. With this the engine runs and seems fine, albeit a bit quieter, until you put a load on it like engaging the blades which causes it to nearly die. So you may want to eliminate this as a possibility by running the engine with one plug wire removed and then the other. If it runs with one wire on alone, but not with the other wire on alone, then you have a nonworking cylinder even though it is receiving spark. Just a thought.

Engine starts and runs okay until I engage blade

I had the same problem on a 21HP, you are running on one cylinder. Take off the valve cover and most likely you will have a/some bent valve push rod(s) which is common on B&S V2 engines. They are cheap to buy but kind of tricky to install and properly adjust.

If the engine runs ok when the blades are not
engaged then the engine is all right. Maybe its a faulty safety blade switch or a wire to the switch is stripped and is earthing to the body. Stephen

Lawnmower loses power when I engage blades

This is most likely a belt problem. Check the deck drive belt that runs from the mower deck to the engine it/s come loose and got stuck between the guides.
