    I got a Briggs that wil not start. Getting plenty of fuel. Almost seems like weak spark. What could be wrong with this? All I get is an occasional pop from it but it doesnt really try to start Has always started right up for the last 4 years.

    Spark plug, wire and ignition magneto, try plug first, magneto should come with new wire attached.

    Thanks. Will try to find a new magneto in the morning. Tried a couple new plugs and none of them seemed any better. Any special tools required for the magneto?

    Have you checked the spark to see if you are getting spark as it comes around?

    Pulling the plug out and touching the electrode to a place on the motor that it will ground out, then pull the recoil. Make sure you let go of it or you will get a little nip. You will be able to tell how much spark you are getting then.

    Yes , check your flywheel key , sounds like that's your problem . Briggs and Straton have CDI ignitions and I've never seen one go bad and I've worked on a bunch of them ! If it has a recoil start on it , there's a special tool needed to remove the recoil clutch . Make sure you replace the key with an aluminum one like the OEM one . Usually that key shears when the engine comes to an abrupt stop when runnung at operating speed . It's a crank and piston rod saving feature , for such occasions . Those engines lead a hard life on those sanders . Most of the failures I've seen on them were due to no oil in the crankcase ! A low oil shutdown switch is a good idea on them , should be standard equipment .

    Does it start with starting fluid?? Could be junk in the carb.
