Dutch 4 Report post Posted March 29, 2002 You're confused? Join the rest of us...... Not sure, but I don't think that 394970 will fit or work on your engine. Don't know anything about them. Your local Briggs dealer should have all the answers. To the best of my knowledge, a regular armature (magneto, coil) builds a high voltage electrical charge. The points tell when that charge is to be sent to the spark plug. A Magnetron also builds a high voltage elctrical charge, BUT there is a little built in "thingy" that tells when that charge is sent to the spark plug. The "thingy" does the same job as the points, therefore the points are no longer needed. Share this post Link to post Share on other sites

Dutch 4 Report post Posted March 29, 2002 Ron, I cut a Magnetron open one time and that piece inside sure looked like a "thingy" to me. What does it look like to you? Share this post Link to post Share on other sites
TimE 0 Report post Posted March 29, 2002 In a previous reply to my post (message # 6725), you stated that it's hard to tell the difference between a regular armatuer (coil,magneto) and a Magnetron. Briggs has a Magnetron Kit available that eliminates the points/condenser. This is just a small module not a magneto. They also have a Magentron magneto available. The question is does the Magnetron magneto still need points or an Magnetron Kit to create spark or is their function incorporated into the magneto itself? I'm only slightly more confused at this point. The Briggs part # 394970. The part is avilable from Jacks for $10.89 at the link below.

TimE 0 Report post Posted March 31, 2002 Thanks for your response. I thought that they might have a do-hickey or a thing-a-ma-jig inside but I was sure. Share this post Link to post Share on other sites
tman 0 Report post Posted April 13, 2002 its a power transistor and it pulses the coil to make the spark. I expierement with electronics a little bit so I know Share this post Link to post Share on other sites
