dying point set symptoms ?

on an old briggs 8 horse vertical shaft can you say that its a real possibility than an unexplained idle with a pop-miss in it only when its not under load and a sputter/die down after its hot after its been under load for a while could be caused by a worn point set ?

runs great and strong otherwise


how do you properly replace and set points on an old 190702 briggs ?


thanks for anything!

Possible ignition problem, I would also check the valve lash in particular the intake and make sure it has proper clearance.

Replacing the points requries removing the flywheel on the top of the engines, the points are under a little cover you will see held on with a couple of screws once the flywheel is off of the engine.

You may need a flywheel puller to get the flywheel off.

I agree.Set the points @ 0.20.then clean any oil and debres off,run a dollar bill through them,a dollar doesn't leave any debres behind.If the well around the points has oil in it clean it out and replace the breaker plunger.

Valve clearances are .005 to .007 intake,and .009 to .011 exhoust
