Listeroid Engines / Where is 38c's flywheel balancing thread?
« on: February 18, 2020, 02:49:04 AM »
First of all, the engine I will be playing with is not a Listeroid...........it's a 6 hp McCormick Deering horizontal gas engine. I bought it years ago from another collector who replaced a damaged flywheel with an identical flywheel from another engine. I've never run it, but he told me it was a "jumper". He'd tried placing stick on lead weights on the new flywheel without success, but I don't think he actually tried to match them. I have yet to fire it up and see what happens.....there might not actually be a problem, but I need to have a plan in place if there is.
My first thought was to build a balancing stand and place the original flywheel on it and see exactly where the heavy spot was. That flywheel would get marked at the heaviest point, removed and the "new" flywheel tested for the heaviest point......then try to get both wheels matched, either with added weights or drilling material from edge of the rim until balanced. This would (should) get both flywheels at least close to each other, then remount and run the engine.
So, with all these thoughts in mind I started to search for 38c's post on Listeroid balancing, but can't seem to find it! Could someone please point me in the right direction?
