Other Things Simplex / SImplex Mechanics/Owners in SW MI, Nothern IN
« on: November 11, 2014, 11:42:47 AM »
Anyone know of an experienced mechanic or owner of a SImplex in the SW MI or northern IN area?

Have been working on a 1947 and just cannot get the thing to run. Had it running a bit, bit the old carb was messed up and all it would do is idle until it flooded. Got a newer replacement carb from Wayne and now all we can get is an occasional fire. We are at about our wits end with this simple SImplex.

Engine & Transmission / Modified flywheel and piston??
« on: September 19, 2013, 05:35:59 PM »
Ok, just started to tear down a 1947 H model engine and have come across a couple of interesting things.

One is the flywheel attachment to the crank.






All the pics of cranks I've sen have a threaded end. I'm guessing that at sometime in the past, someone buggered up the threads and resorted to welding the thing on.  ???

Item #2....the piston.





Ok, I've slotted or drilled holes in 2-stroke pistons on the exhaust side when there was a bridged exhaust port. I've also have had pistons with a window cut into the intake side. However I've never come across a piston with slots cut thru the intake side. And yes, I mean cut thru...all the way thru the skirt.

Are my assumptions correct that these are non-standard?
