Briggs Stratton no Spark
|Shirley H||I have a 3 HP Briggs Stratton Horizontal Engine
Model 80202 that has no Spark. I tried a new Spark Plug but get no Spark. What do I look for next?
|Joe||If eng has a remote stop sw disconnect sw to make sure sw not bad,if still no spark with sw disconnected,then clean points & check gap(.020")if points pitted or worn replace same,points & condenser come as a set,if still no spark after cleaning/replacing points then ign coil bad.you'll have to remove flywheel cover & flywheel as points are located under flywheel.
|Shirley Hill||Thanks Joe I removed flywheel and points look good. Is there any testing I can do with a contunity tester ? Any way I can check the coil ?
|Joe||Points may look good but should be checked,disconnect wire on points,connect an ohmmeter or powered test lite to coil lead terminal on points & other lead to eng block,remove spark plug,rotate eng by hand several times slowly,you should get a 0 ohms or BRIGHT lite each time points close,if high ohms reading or dim lite,clean points & recheck,if still no change replace points & condenser,as same are pitted or worn,also remove any rust on flywheel magnets & check air gap on coil legs(.006-.010")if points are good then coil bad,briggs gives no info in service manual for testing coil,as you need a coil tester to do so,most dealers have one & will probably check n/c
|Shirley H||Thanks Joe, I bought from Napa auto parts new points / cond and installed them. The kit came with a flywheel key-spark plug-.020 gauge-push rod & lube-plus plastic tool to remove wire from cond. Quite a kit from B/S I thought. Got spark now & runs good. Thanks again..
