The first 2 digits of the "CODE" will identify the year of a Briggs engine.
So, you can see Rick's is a 73 according to his "CODE". I am told that all
of them went electronic on their ignitions by 1982.

I have had lots of troubles with the 10hp single vertical engines sitting outside
and getting water behind the flywheel and sometimes into the points, but
the only twin I have ever had (a 79) has very well-protected points between
the cyls. I have never converted older engines to electonic ign, so I am
curious how that goes.

Hi All,

I hope one of you can shed some light on a problem my Dad and I have encountered.

My Dad has a B&S 16 hp engine in his 1973 Gilson S16 lawn tractor. After 27 years of faithful service, it has developed what we believe to be an ignition problem. The spark at the plug is weak to non-existent.

Our observation is that the ignition points are open during the majority of the rotation of the crankshaft, close shortly before the plug should fire and open at the time the plug fires....only to stay open until the cycle repeats.

This seems counter to what we've observed on other engines. That is, usually we observe the points to remain closed during the entire crankshaft rotation and open at the time the plug fires, then close again a few degrees later and remain closed until opening again to fire the plug.

Our question: "Is what we're observing on this engine usual for this model, or other B&S engines?"


We now assume what we're observing on the points is incorrect, and we think that the coil is not getting sufficient time to build up a sufficient magnetic field since the points are closed for such a brief period of time. Although we're not sure why this would happen, it would imply a problem with the ignition points plunger mechanicals.

On the other hand, if this is normal for these engines, then we will assume that the magneto/coil are creating a weak spark.

The numbers for the engine are: Mod #:326434, Type #:0134-02, Code #:7304031, if that means anything to anyone.

Thanks in advance for any help you can give.

Sincerely,

Rick

i have a 67 12hp gilson B&S and had the same problems your having i finally pulled the head and found that the intake lifter was not closing all the way open about a 16th, so no compression will not start. i dont know if it is fixable or if you can find parts. would like to get it fixed if anyone has an idea let me know thanks hope it helped terry

HEY VON ,
I WAS READING YOUR POST ABOUT ELECTRONIC IGNITION FOR A B/S 16 HORSE GLISON TRACTOR. I HAVE ONE THAT THE POINTS ARE MISSING SO THAT SOUNDS EASIER THAN TRY TO FIND ALL THE HARDWARE AND STUFF TO TRY AND USE POINTS I WAS HOPEING YOU WOULD BE ABLE TO TEELL ME WHERE I MIGHT FIND ONE THANK YOU
