If you find that your Briggs engine is very hard to start then do we have a couple of ways to determine what this issue entails?

Briggs and Stratton Part – Briggs Engine Hard to Start

We here at this Briggs and Stratton part posting site really know that you all simply adore your Briggs mowers. Of course you do and that is why it is so vitally important that we offer you some lesser known methods and ways of getting to the bottom of that 5 to at times 15 year old Briggs mower.

Old Sparkie

First step is to make certain that the ignition switch is in the on position. The gear should be marked as neutral and then you will need to either push a button or pull a cord. If still no action then it is time to check out Old Sparkie!

Blue Spark Search

Next, check for a spark by removing the spark plug and make certain that you ground the “hex” part of the spark plug to a bare metal part of the engine. After cleaning up any combustibles such as oily or fuel-filled rags and the likes it is time to create a spark. Grab a hold of the starter rope or push the button on electric starters and look for a blue spark in the plug gap area. If you are successful here and see a bright blue spark dance across the gap then all you have to do now is to proceed to the carburetor area.

  • Being over 60 years old, I have long been a fan of the Briggs engines of the past. I purposely selected my pressure washer with the Briggs engine over Honda and Techcomsa engines. The unit started fine right out of the box and I ran it for about 6 hours. Since that time it refuses to start without pouring gas directly into the spark plug hole no matter how long I crank. The engine will then start and stop a couple times before running fine. Each time the spark plug has to be removed and more gas poured in. Apparently, there is no choke on this unit that would allow manually rich starting. Yes, it has fresh gas and yes the switch is on and yes the gas in turned on. This unit only has at the most 15 hours on it so it is essentially new but I have had it to the point that I avoid having to use it. If you have any recommendations other than selling it to some suspecting sucker and buying a different brand I am willing to listen.

  • Would assume the automatic choke is not working / working correctly. It may need replace, but it might only need the choke arm repositioned. How long was it in between the first and second time you used it? If it sat for a while it could possibly be a fuel problem.

  • Two days from the first to the second time I used it.
    I have have Briggs engines of older vintage start on the second pull with 6 month old fuel not that long ago. As I said I have had this for about a year but it starts so hard, I seldom use it.

  • I have a briggs and straton 17 hp OHV engine, model #31C707, type # 0175E1. The starter will not turn it over. I have put in a new starter, selenoid and battery. I have adjusted the valves and can see the slight movement on the intake (lower) valve which I think is for the compression release. .0025 on the intake and .005 on the exhaust.
    I did install a fuel shut-off valve because of a flooding problem when the engine was sitting and not running for two weeks between yard mowings. I think that problem could be the auto fuel stop in the carburator. But now there is no flodding problem.
    I can start it if I jump it to my car battery, for extra amps.
    It seems to still have a compression issue. (even with the fuel shut off)
    What advice can you give?
    Could the cam still be bad, even though I can see it move for the compression release?
    I even burned up one starter already.

  • Thanks for you comment. Here is a message from our service staff.

    I am not sure what this is on, but it sounds like you might have a problem with the amount of current going to the starter. I would make sure that you have heavy enough cables from battery to starter. Make sure the decompression is working (need to check the compression to make sure it is not too much while starting). The valve specs are as follows. Intake .003 – .005 Exhaust .004 – .007. I doubt this is the problem, but check to make sure that the flywheel key is not sheared. Hope this is some help.
