Stepney 2,354 #1 Posted January 11, 2013 It speaks for it's self... They say the older engines were simple, but this 1920-21 Associated Wonder-Boy 2 horse begs to differ! To make matters worse, there is that gearing, it's fun when the mag is serviced to re-time... Oh, by the way, just to ask a goofy question, this engine, yes, it has a magneto, but no, there isn't any spark plug... And I don't mean it's not in the head. So, how do you figure this engine was fired? HINT, there are no point's on the Mag... Quite the timing system... huh? Spenser. Share this post Link to post Share on other sites
groundhog47 347 #2 Posted January 11, 2013 No knowledge of this at ALL, but is that helical gear just a transitional gear or does it drive something else. And of course Ipresume it's not diesel, steam, pneumatic. VERY INTERESTING, Spenser, doesn't all add up. Please let us know, before I see my shadow! Share this post Link to post Share on other sites
groundhog47 347 #3 Posted January 11, 2013 On Keith's Associated Engine(s) website they say the engine is fired by an igniter???. Itn shows that config in you picture on one of the pages. Couldn't fig just how to capture the link, but give the early history and will dig deeper. If your mag has any sort of slider/knife type switch they say it can be bat, coil or mag ignited and switched while runnin'. So that rules out diesel, steam, pneumatic, so I pick D.

Stepney 2,354 #4 Posted January 11, 2013 Oh, she runs, and runs well! I guess I mistyped that, I meant no plug as a joke. I brought it up with the schools Automotive teacher, he thought I was off my rocker! You're right, it is an igniter, and no, it's just an idler gear. You have to start it off a low-tension coil, because the hand-crank doesn't spin the mag fast enough. It WAS a pain timing it, though... I've got her running around 60-70 RPM now! I never knew quite WHY they did that... The SIMPLICITY engines were even worse! Share this post Link to post Share on other sites
groundhog47 347 #5 Posted January 13, 2013 The old tecknowlegy is somethin'. Some of the olden ones are still in modern use, shucks, if it works and is efficient enough, why not. I had an old brick crusher that I recently gave to my neighbor that flat belt ran off one similar I'll bet. Bet you'll enjpy showin' that one! Share this post Link to post Share on other sites
