5116 won't run

[brockway 0]

Little confused I am getting spark with the plug out and on a bolt. And when I try to start it,it doesn't start and the plug comes out they are wet? So it is getting fuel.Even sprayed starting fluid in the cylinders.

Bad or discharged battery? It takes a certain RPM to get spark from a magnetron ignition. RPMs may be achieved without compression but not against.

Replace plugs.

Is it possibly out of time? Partially sheared key?

I am helping a friend out with this tractor.How would I know if the key is sheared?

You have to pull the flywheel to check the key. Probaly just a couple taps on the crankshaft to confirm.

Like Maynard said replace the plug. Sometimes they wont fire under compression.

Our grandson just had a coil failure in his 16 twin Briggs. It would run ok until it got hot.

I have replaced quite a few of those coils on the twins. Might just be a weak spark from a failing coil but the easiest thing to try is the plugs first.

I got it fixed it was a bad coil Thanks for the help
