CHECK BREAKER POINTS
burned, dress smooth with file or fine stone. Do not
use emery paper or emery cloth. Measure gap with
thickness gauge; gap points at .020-inch (0.51 mm).
Ignition breaker points, Figure 16, must be correctly
gapped. Crank engine to fully open breaker points
(1/4 turn after top center). Loosen locking screws (A)
and turn cam (B) tQ adjust. Tighten breaker points
and recheck gap.
Ignition points should break contact just as the 20-
degree timing mark aligns with the flywheel timing
mark. Final timing is corrected by properly shifting
the breaker point box on its mounting and using a
timing light. If specified timing cannot be obtained by
positioning the breaker box, make sure timing marks
on gears are aligned.

0.019" is the breaker point setting. You can find this in your service manual.

Hi marie hourig...

Set your gap between .18 and .20...if you do not have a feeler gauge to get the clearance right, then you can use a paper match book cover...it is approximatly the same thickness as you need.
Please take time to rate me

Most contact breaker ignition systems, the points should just break before tdc, once you have set the correct breaker gap, you should slacken the screws securing the whloe back plate and rotate either way, the manufacturer of the engine should tell you how many degrees before tdc they should open, small engines normally have marks on the flywheel to tell you.

Run it at 25-1 with a good two stroke oil, base settings are 1 turn on the high and 1 1/4 on the low, you will need to fine tune from there.

Go to arboristsite.com.They can tell you everything you could ever need to know about that saw.You do need to sign up.Its free to do so.I am sorry I just don't the gap off hand.But they will help you with the carb and any other problem FREE!!!

Try 15 to 17 thousands

Remove the flywheel to get at the parts. If the breaker cam is on the flywheel and there are no access holes to allow point adjustment, you will need a cam tool in order to set the point gap correctly. Most modern saws don't use points/condenser--they use a self-contained ignition module that fires the plug every rotation. If it doesn't work, replace the module! Hope this helps!

The point gap on all Briggs and Stratton engines is .020 inch

You should be safe with a 32:1 mixture unless you are a logger. And any Bar Chain Oil should work fine.
